18 Of The Best Function Rooms In Dublin

Choosing the Right Function Room in Dublin

Function rooms in Dublin range from smaller private spaces and traditional pub rooms to hotel suites, rooftop venues and larger event spaces for 200+ guests.

The best function room in Dublin will depend on far more than how many people it can hold. A room that works perfectly for a 100-person drinks reception may not suit 100 guests for a seated dinner, while a space designed for a late-night party may be completely wrong for a corporate presentation or networking event.

When we source function rooms for clients, we look at how the event will actually work. Guest numbers, privacy, room layout, food and drink, private bar facilities, AV, entertainment, accessibility and location can all influence which venue makes the most sense.

Dublin has everything from smaller private rooms and traditional pub spaces to hotel suites, rooftop venues and larger function rooms for 200+ guests. Some work particularly well for corporate events, while others come into their own for company parties, milestone birthdays, engagements, private dining and celebrations with live entertainment.

We've selected the 18 function rooms below based on the types of briefs we regularly receive and, importantly, how the spaces can actually be used. Alongside the key details for each venue, you'll find our Find a Venue Tip, highlighting the practical details that can make a real difference when choosing between them.

If you're not sure which room fits your event, Find a Venue can compare suitable options based on your numbers, budget and requirements and help you find the right space.

Iveagh Garden Hotel – Iveagh Suite

Best for: Corporate events, Christmas parties, company parties, private dinners, milestone celebrations and larger receptions
Guests: Up to 220 for a reception, 100 for a banquet or 80 for a dinner dance
Privacy: Fully private function space with its own entrance
Private bar: Yes
Food: Private dining, canapés and event catering
AV & entertainment: Projector and screen, two 50-inch screens and roaming microphone
Outdoor space: Private terrace
Location: Harcourt Street, Dublin 2

The Iveagh Suite is a flexible city-centre function room that can move comfortably between a corporate event during the day and a private party or dinner in the evening. Its private entrance, bar and terrace help keep the event self-contained, while the AV facilities make it equally practical for presentations, speeches and company events.

The hotel also has Elle’s Suite, giving larger events the option of using more than one space and creating different stages to the occasion rather than keeping guests in the same room throughout.

Find a Venue Tip: For larger events, you don't necessarily have to choose between Elle's Suite and the Iveagh Suite. The two spaces can work particularly well as part of the same event, with welcome drinks or a more formal first part of the evening in Elle's Suite before guests move downstairs to the Iveagh Suite for the main party. It's a useful way of creating two distinct stages to the event without moving guests to another venue.

37 Dawson Street – Whiskey Bar

Best for: Birthday parties, Christmas parties, engagement parties, corporate drinks, networking events and smaller private celebrations
Guests: Around 45–50 standing in the Whiskey Bar
Privacy: Private function space with separate access
Private bar: Yes
Food: Finger food and party food options
AV & entertainment: AV facilities available for corporate and private events
Location: Dawson Street, Dublin 2

Hidden towards the rear of 37 Dawson Street, the Whiskey Bar is a strong option when you want the atmosphere of one of Dublin's livelier late-night venues without putting your group into the middle of the main bar. Its darker, vintage-style interior lends itself particularly well to drinks-led events, birthdays and evening celebrations.

37 Dawson Street also has other spaces for larger groups, so the Whiskey Bar isn't necessarily the right choice simply because you're holding an event there. For a group of around 45–50 looking for something more intimate and self-contained, however, it's one of the more interesting options in the venue.

Find a Venue Tip: If you're booking the Whiskey Bar, there's a useful advantage that isn't immediately obvious. Guests can access the room from Anne's Lane, rather than having to make their way through the busy main entrance on Dawson Street. For a private event, that can make arrivals feel much more separate from the main venue.

The Bridge 1859 – River Room & 1859 Room

Best for: Corporate drinks, Christmas parties, birthday parties, engagement parties, networking events and private celebrations
Guests: Up to 60 in either room, or up to 120 when both spaces are combined
Privacy: Fully private function rooms
Private bar: Yes
Food: Finger food and party food options
AV & entertainment: TV screens in the 1859 Room; the River Room has a sound system for your own music
Location: Ballsbridge, Dublin 4

The Bridge 1859 has two private function rooms that work particularly well for medium-sized events. The River Room overlooks the River Dodder, while the 1859 Room offers a flexible setting for parties and corporate gatherings. Each room has its own bar and can accommodate up to 60 guests, with the option of combining the spaces for larger groups of up to 120.

Its Ballsbridge location is particularly convenient for companies based around Dublin 4, while the combination of private rooms, food and a lively pub atmosphere makes it equally suitable for celebrations that want to become more informal as the evening progresses.

Find a Venue Tip: If you're considering The Bridge for a private or corporate event, check your preferred date against the Aviva Stadium and RDS event calendars. Major match and concert days can make Ballsbridge considerably busier, affecting traffic, parking and guest arrival times. That atmosphere can be a plus for some events, but if you're planning something more private or relaxed, we'd consider the wider area schedule when choosing dates.

The Black Door – Georgian Bar & Piano Bar

Best for: Corporate parties, milestone birthdays, engagement parties, drinks receptions and late-night celebrations
Guests: Up to 60 in the Georgian Bar and up to 150 in the Piano Bar
Privacy: Private hire options available
Private bar: Yes
Food: Canapés and party food, with more substantial catering options available for private events
Entertainment: Live music and DJs can be arranged
Location: Harcourt Street, Dublin 2

The Black Door is particularly well suited to events where the evening atmosphere matters as much as the function space itself. The Georgian Bar provides a more intimate setting for smaller groups, while the downstairs Piano Bar gives larger parties room for drinks, entertainment and dancing.

Its late-night character makes it a natural fit for company parties and private celebrations rather than formal daytime events. For groups that want a private space but still want the feel of a Dublin late bar as the evening develops, it offers something quite different from a conventional hotel function room.

Find a Venue Tip: If food is an important part of your event, don't assume The Black Door is limited to standard party food. Its connection with neighbouring 1900 Restaurant can open up more substantial dining options for private events. It's worth discussing the food requirements when enquiring, particularly if you want the atmosphere of The Black Door but something more substantial than finger food or canapés.

Grand Central – Private Function Room

Best for: Birthday parties, corporate gatherings, engagement parties, office nights out and private celebrations
Guests: Best suited to groups of around 50–80
Privacy: Fully private function room with its own entrance
Private bar: Yes, with a dedicated bar team
Food: Party platters and two or three-course dining options
Location: O’Connell Street, Dublin 1

Grand Central’s private function room offers a self-contained event space in a particularly central location. With its own entrance and private bar, guests can arrive directly into the function rather than having to move through the busy main pub, while the dedicated bar team keeps the event separate once everyone is inside.

The room is particularly suited to evening celebrations and drinks-led events. Its darker, more atmospheric setting works well for birthdays, engagement parties and company nights out, but it is worth considering the style of your event if natural daylight is an important part of the brief.

Find a Venue Tip: Grand Central’s private function space is downstairs, with its own direct street entrance, so guests can arrive without coming through the busy main bar. It’s a darker, more atmospheric space rather than a bright, daylight-filled room, which makes it particularly well suited to evening parties and late-night events. If natural light is important to your event, we’d consider that before choosing this space.

grand central private function room dublin

The Harcourt Bar – Barney’s Bar & The Shaw Room

Best for: Corporate parties, Christmas parties, milestone birthdays, engagement parties, drinks receptions and larger private celebrations
Guests: Up to 130 for a cocktail-style event or 85 for a banquet when the rooms are combined
Privacy: Two private interconnecting function rooms that can be used separately or together
Private bar: Yes
Food: Private dining, buffets and party food options
AV & entertainment: Projector and screen, roaming microphone and PA system
Outdoor space: Direct access to the all-weather garden
Location: Harcourt Street, Dublin 2

Barney’s Bar and the Shaw Room give The Harcourt Bar plenty of flexibility for events where the size or format may change. The rooms can operate independently for smaller groups or be opened up together to create a larger function space, while the connection to the garden adds another dimension for events where guests are likely to move around during the evening.

The combination works particularly well for company parties and larger celebrations where you want separate areas for food, drinks and entertainment without splitting the event across different parts of the venue.

Find a Venue Tip: Barney’s Bar and the Shaw Room can be booked separately, but for larger events we’d consider using the two together. One room can work well for a smaller group of around 40–50, while combining them creates a much more flexible layout for larger cocktail-style events or corporate functions. The connection with the hotel’s all-weather garden can also create a useful indoor-outdoor flow, particularly when guests are moving between drinks, food and entertainment.

Fitzpatrick Castle Hotel – Albert & Behan Suite

Best for: Corporate events, Christmas parties, company parties, summer events, private dinners and larger celebrations
Guests: Up to 220 for a banquet
Privacy: Fully private function space
Private bar: Yes
Food: Banquet dining, private dining and BBQ options
AV & entertainment: AV facilities available for corporate and private events
Outdoor space: Direct access to the back gardens
Location: Killiney, South Dublin

Fitzpatrick Castle offers a very different setting from the city-centre function rooms on this list. The Albert & Behan Suite combines the facilities of a hotel function room with direct access to the gardens, making it particularly interesting for events where you want to use both indoor and outdoor space.

For significantly larger events, the Prince Regent Suite can accommodate up to 400 guests for a banquet and 600 theatre-style. That gives the hotel considerable flexibility, from corporate events and private dinners through to major company celebrations and large-scale functions. For a more formal company dinner, you can also explore our guide to Gala Dinner Venues in Dublin.

Find a Venue Tip: Don’t overlook the outdoor space at Fitzpatrick Castle when planning a corporate event. The Albert & Behan Suite has access to the back gardens, which can be used for a private BBQ, while the hotel’s extensive grounds can also accommodate outdoor team-building activities. For a summer company event, that gives you the option of combining a private indoor function room with outdoor food or activities rather than treating the hotel purely as an indoor venue.

The Dropping Well – Bank Room & Dodder Room

Best for: Corporate events, milestone birthdays, Christmas parties, private dinners, family celebrations and larger parties
Guests: Bank Room up to 130 for dinner or 200 standing; Dodder Room up to 50 seated
Privacy: Fully private function rooms
Private bar: Yes
Food: Set menus, hot buffets and party platters
Outdoor space: Riverside setting within the wider venue
Location: Milltown, Dublin 6

The Dropping Well offers two quite different function spaces, making it suitable for both smaller gatherings and significantly larger events. The Bank Room is the main choice for bigger celebrations, with space for up to 200 standing, while the upstairs Dodder Room provides a more intimate setting for smaller groups.

Its location beside the River Dodder gives the venue a different feel from a typical city-centre function room, while Milltown Luas stop is within walking distance. For groups based around South Dublin, it can be particularly useful when travelling into the city centre isn't essential to the brief.

Find a Venue Tip: For a smaller daytime event, the Dodder Room is worth considering rather than automatically choosing the larger Bank Room. Its upstairs position and outlook over the River Dodder give it a brighter feel, which can work particularly well for daytime celebrations, meetings and smaller corporate events. It's a good example of where the atmosphere of the room can be just as important as its maximum capacity.

O’Neill’s Merrion Row – The Green Room

Best for: Corporate events, Christmas parties, birthday parties, private dinners, quizzes and smaller company celebrations
Guests: Up to 50 seated or 80 with a mixture of seated and standing guests
Privacy: Fully private function room
Private bar: Yes, with a dedicated bartender
Food: Group dining and party food options
AV & entertainment: TV with HDMI connection, microphone and PA system
Accessibility: The Green Room is not wheelchair accessible
Location: Merrion Row, Dublin 2

Located on the second floor of O’Neill’s Merrion Row, the Green Room is a particularly practical option for groups that want a traditional Dublin pub setting but still need the facilities of a proper private function room. Its combination of a private bar, AV equipment and flexible capacity makes it suitable for everything from birthday celebrations to company events and corporate quizzes.

Unlike some private rooms where guests need to move between different floors for drinks or facilities, the Green Room keeps the main elements of the event together. That can make a noticeable difference to how well the room works once the event is underway.

Find a Venue Tip: For groups of around 50–80, the Green Room is particularly practical because everything your guests need is on the same floor. It has its own private bar with a dedicated bartender and bathrooms on the same level, so guests aren’t constantly moving between floors during the event. It also has a screen, microphone and PA system, making it a particularly useful option when you’re combining a private party with speeches, presentations or a quiz.

Lost Lane – The Library

Best for: Corporate parties, engagement parties, Christmas parties, birthdays, networking events and day-after wedding celebrations
Guests: Up to 100
Privacy: Fully private function room
Private bar: Yes
Food: Party platters and event catering options
AV & entertainment: Private sound system, microphones, piano, sound desk and speakers
Outdoor space: Private rooftop terrace
Location: Adam Court, just off Grafton Street, Dublin 2

The Library sits above Lost Lane’s main live music venue and gives groups a private event space right in the centre of Dublin. With its own bar, toilets, sound system and rooftop terrace, it works particularly well for events that want the atmosphere of a late-night venue without putting the group into the main public space downstairs.

The room is also well equipped for entertainment, making it a strong choice for company parties, engagements and celebrations where live music or a DJ forms part of the evening. The terrace is a particularly useful addition during the warmer months.

Find a Venue Tip: One of the big advantages of The Library is its rooftop terrace. The room has its own bar, toilets and outdoor space, so a private event doesn’t have to be entirely indoors. For a summer party, engagement or day-after wedding celebration, it gives guests somewhere to move between the function room and outdoor space without leaving the event.

Rody Boland’s – Mick Mac’s

Best for: Christmas parties, birthday parties, company nights out, engagement parties, reunions and informal private celebrations
Guests: Up to 150
Privacy: Private function space
Private bar: Yes
Food: Finger food and full meal options depending on the event
Entertainment: Live music and DJs at weekends
Location: Rathmines, Dublin 6

Rody Boland’s is a good fit for groups looking for a private function space within a lively Dublin pub rather than a formal hotel setting. Mick Mac’s provides a dedicated upstairs space for larger groups, while food and entertainment can be incorporated into the evening depending on the type of event.

It is particularly suited to celebrations where the event becomes more informal as the night progresses. The weekend entertainment is part of the attraction, but it also means the timing of speeches, food and other organised elements deserves some thought.

Find a Venue Tip: If your event includes speeches, a quiz or cake cutting, we’d aim to have those elements finished before the weekend entertainment begins at around 10 pm. That gives you the quieter part of the evening for food and speeches, before the venue becomes livelier and the event can naturally move into the party.

Not Sure Which Function Room Is Right for Your Event?

Tell us your date, guest numbers, budget and what you're planning, and we'll help you compare suitable function rooms in Dublin and find the space that fits your event.

Merchant’s Arch – Private Function Room & Mezzanine

Best for: Corporate parties, Christmas parties, milestone birthdays, private dinners, wedding & engagement parties and celebrations with live music
Guests: Up to 150 seated in the private function room; up to 40 seated on the Mezzanine
Privacy: Fully private function room or semi-private Mezzanine
Private bar: Yes, in the private function room
Food: Sit-down dining, buffets, canapés and finger food
AV & entertainment: Projector, two TVs and AV facilities in the private room; live music can be enjoyed from the Mezzanine
Location: Temple Bar, Dublin 2

Merchant’s Arch gives you two very different ways to host an event in the heart of Temple Bar. The main function room is the choice when you want complete privacy, with its own entrance, bar and bathrooms alongside AV facilities and space for up to 150 seated guests. It works particularly well when you want the entire event contained within one dedicated space.

For smaller groups, the Mezzanine offers a different experience. It is semi-private and overlooks the main bar and live music below, allowing guests to have their own area while remaining part of the atmosphere of the venue.

Find a Venue Tip: If you don't need a completely private room, the Mezzanine can be a clever option for a smaller event. It overlooks the main bar and live music below, so your group can have its own dedicated space while still enjoying the atmosphere and entertainment without having to arrange and pay for separate live music.

The Harbourmaster – Greenhouse Function Room

Best for: Corporate events, summer parties, product launches, networking events, milestone celebrations and larger private parties
Guests: Up to 150 seated or 200 standing
Privacy: Fully private function room
Private bar: Yes
Food: Private dining, event catering and BBQ options
Outdoor space: Private first-floor terrace and decking
Location: Custom House Dock, IFSC, Dublin 1

The Greenhouse is one of the larger private function rooms on this list and combines a dedicated indoor event space with its own outdoor terrace. Floor-to-ceiling windows overlooking the Docklands give the room plenty of natural light, while the private bar and catering facilities allow the event to remain self-contained.

Its IFSC location makes it particularly useful for corporate events, launches and networking functions, but the terrace changes what the room can offer during the warmer months. Rather than choosing between an indoor function room and an outdoor summer venue, groups can incorporate both into the same event.

Find a Venue Tip: For a summer event, the Greenhouse is much more than an indoor function room. Its first-floor terrace can be used for BBQs, allowing you to combine the private room, its own bar and the outdoor decking as part of the same event. For a corporate summer party, this creates a particularly useful indoor-outdoor flow without guests having to move downstairs to the main beer garden.

Lennan’s Yard – Whiskey Bar

Best for: Corporate hospitality, Christmas parties, client dinners, milestone birthdays, engagement parties and smaller private events
Guests: Up to 26 seated for dinner; larger groups can be accommodated for drinks and light bites
Privacy: Fully private
Private bar: Yes
Food: Set menus, light bites and drinks reception options
Outdoor space: Private terrace overlooking the courtyard
Location: Dawson Street, Dublin 2

The Whiskey Bar at Lennan’s Yard is a strong option when you want a genuinely private city-centre space without moving into a large traditional function room. Its Dawson Street location makes it particularly convenient for company events, client entertaining and private celebrations where guests are travelling from different parts of Dublin.

The room works for a sit-down meal of up to 26 guests, while larger groups can use it for a more informal drinks and food reception. Its private bar and adjoining terrace also give the space more flexibility than its relatively intimate size might suggest.

Find a Venue Tip: The private terrace is one of the reasons we'd consider the Whiskey Bar over a conventional small function room. It gives guests somewhere else to move during the event, which can make an intimate space work particularly well for arrival drinks, networking or a less formal company gathering.

If you're planning something during the warmer months, you can also explore our guide to Summer Party Venues in Dublin for more venues with terraces, gardens and outdoor event spaces.

Radisson Blu Royal Hotel Dublin – Sky Suite

Best for: Corporate events, Christmas parties, private dinners, presentations, drinks receptions and smaller company celebrations
Guests: Up to 50
Privacy: Fully private function space with private lift access
Private bar: Yes
Food: Private dining, canapés and event catering
AV & entertainment: Hotel AV facilities available for meetings, presentations and private events
Outdoor space: Wraparound balconies
Location: Golden Lane, Dublin 8

Located on the seventh floor of the Radisson Blu Royal Hotel Dublin, the Sky Suite is designed for smaller events where the setting is as important as the capacity. Panoramic views across Dublin, wraparound balconies and a dedicated bar give it a very different feel from a conventional hotel meeting or function room.

With a maximum capacity of 50, it works particularly well for smaller corporate events, Christmas parties, private dinners and drinks receptions. The hotel's larger function spaces also mean there are alternatives available when the brief or guest numbers require more room.

Find a Venue Tip: The Sky Suite works particularly well when you want an intimate event with a sense of occasion, but we'd be careful about booking it if your guest list is likely to grow. If your numbers are approaching 50, consider one of the hotel's larger function spaces from the outset. That gives you more flexibility for late additions and allows you to choose the layout that works best for the event rather than simply trying to fit the maximum number of guests into the room.

radisson blu royal sky suite dublin

The Goat Bar & Grill – Drumaville Suite & Anvil Room

Best for: Corporate parties, milestone birthdays, company nights out, private dinners and larger celebrations
Guests: Drumaville Suite up to 120 dining or 250 with a mixture of seated and standing guests; Anvil Room up to 70 seated or 110 mixed
Privacy: Private function rooms
Private bar: Yes
Food: Sit-down dining, buffets and finger food
Outdoor space: Heated beer garden available within the wider venue
Location: Goatstown, Dublin 14

The Goat gives groups a choice of function rooms rather than trying to make one space work for every event. The Drumaville Suite is the larger option and can accommodate everything from private dining to sizeable company parties, while the Anvil Room is better suited to smaller groups looking for a more intimate, self-contained setting.

That flexibility makes The Goat particularly useful when guest numbers or the style of the event are driving the decision. It also offers a very different option from the city-centre venues on this list for companies and guests based around South Dublin.

Find a Venue Tip: If you’re planning a more relaxed party or company night out, don’t automatically choose the largest function space at The Goat. The Anvil Room has its own bar within the room, which works particularly well for a drinks-led event because guests aren’t continually leaving the function space to order at another bar. For the right-sized group, that helps keep the party together and creates a more self-contained atmosphere.

the goat bar and grill private function room dublin

The Dean Dublin – Blue Room

Best for: Corporate events, Christmas parties, private dinners, product launches, drinks receptions and milestone celebrations
Guests: Up to 120 for a cocktail reception or 60 for a seated banquet
Privacy: Fully private function room
Private bar: Yes
Food: Private dining, canapés and event catering, with a dedicated kitchen
AV & entertainment: Suitable for presentations, DJs and live entertainment
Location: Harcourt Street, Dublin 2

The Blue Room is one of The Dean Dublin’s main private event spaces, combining large windows overlooking Harcourt Street with its own bar and dedicated kitchen. It can accommodate up to 120 guests for a standing reception, making it a strong option for company parties, Christmas events, launches and drinks-led celebrations in the city centre.

The important distinction is how dramatically the usable capacity changes depending on the event. A standing drinks reception, seated dinner and party with substantial entertainment all use the room differently, so the headline capacity shouldn't be considered in isolation.

Find a Venue Tip: Don't judge the Blue Room by its 120-person standing capacity alone. For a seated dinner, it accommodates up to 60 guests and the banquet setup is limited to long tables. Entertainment can also reduce the practical standing capacity to around 80–100 guests. If you're planning a larger seated event or need significant floor space for a band, DJ setup or other entertainment, we'd look at the Marshall Room instead rather than trying to make the Blue Room fit the brief.

4 Dame Lane – The Loft

Best for: Corporate parties, Christmas parties, product launches, networking events, milestone birthdays and drinks receptions
Guests: Up to 250 standing
Privacy: Private hire available
Private bar: Yes
Food: Party platters and event catering options
AV & entertainment: Own DJ booth with facilities for music and entertainment
Location: Dame Lane, Dublin 2

The Loft gives larger groups a private event space above the main bar in one of Dublin's busiest nightlife areas. Its capacity and less formal style make it particularly well suited to company parties, Christmas events and launches where you want plenty of room for guests to mingle rather than a traditional hotel function-room setup.

The private bar and DJ facilities also mean entertainment can form a central part of the evening. For corporate groups, the more relaxed layout can work particularly well when the objective is to get people mixing rather than keeping everyone around fixed tables.

Find a Venue Tip: For a company party or networking event, make use of the entertainment already built into The Loft. Alongside its private bar and DJ setup, the room has games including ping pong, foosball and retro board games. Rather than treating them as background features, we'd incorporate them into the layout so guests naturally have something to do between drinks, food and dancing. They can work particularly well as informal icebreakers when you're bringing together colleagues who don't necessarily know each other.

How Function Room Hire Works in Dublin

There is no standard pricing structure for function rooms in Dublin. How you pay will depend on the venue, date, guest numbers and type of event. The most common arrangements are:

  • Room hire fee: A fixed charge for exclusive use of the function room.
  • Minimum spend: Instead of a hire fee, some venues require your group to spend a minimum amount on food and drinks.
  • Minimum guest numbers: Some venues waive the room hire once an agreed number of guests are attending.
  • Food packages: The room may be provided without a separate hire fee when a minimum number of guests order finger food, canapés, a buffet or a set menu.
  • Peak-night conditions: Thursday, Friday and Saturday nights, Christmas dates and other high-demand periods can have different minimum-spend or hire requirements.

A function room advertised with a low or zero hire fee isn't necessarily the least expensive option overall.

When comparing venues for our clients, we look at the total cost and requirements of the event, including the room, food and drink, AV, entertainment, timings and any minimum-spend conditions. This gives you a much clearer comparison than looking at the room hire charge alone.

Planning a Christmas Event?

Function rooms can work particularly well for company Christmas parties where you want a private bar, food and entertainment in one space. You can also compare our Christmas Party Venues in Dublin for more ideas across hotels, restaurants, bars and dedicated event spaces.

Best Function Rooms in Dublin by Group Size

Capacity can change considerably depending on whether you're planning a seated dinner, standing reception or event with entertainment. As a starting point, these are some of the rooms from our list worth considering at different guest numbers:

  • Up to 50 guests: Merchant’s Arch Mezzanine, 37 Dawson Street Whiskey Bar, Radisson Blu Royal Sky Suite and O’Neill’s Green Room for seated events.
  • 50–80 guests: Grand Central, The Bridge 1859, The Harcourt Bar’s individual function rooms, The Goat’s Anvil Room and O’Neill’s Green Room.
  • 80–120 guests: Lost Lane’s Library, The Dean’s Blue Room for standing receptions, The Bridge 1859 with both rooms combined and The Goat’s Anvil Room or Drumaville Suite depending on the layout.
  • 120–200 guests: Merchant’s Arch Private Function Room, Rody Boland’s Mick Mac’s, The Black Door Piano Bar, The Harbourmaster Greenhouse, The Dropping Well Bank Room and The Harcourt Bar with Barney’s Bar and the Shaw Room combined.
  • 200+ guests: The Goat’s Drumaville Suite, 4 Dame Lane’s Loft, Fitzpatrick Castle’s larger suites and selected larger hotel function spaces.

Remember: maximum capacity doesn't necessarily mean comfortable capacity. A room that accommodates 120 people standing may hold considerably fewer for dinner, while a band, DJ setup, dance floor, stage or other entertainment can reduce the usable space further. We always recommend choosing the room around how the event will work, rather than simply matching your guest number to the venue's maximum capacity.

Frequently Asked Questions About Function Rooms in Dublin

How much does it cost to hire a function room in Dublin?

The cost of hiring a function room in Dublin varies considerably. Some venues charge a fixed room hire fee, while others operate on a minimum spend or waive the hire fee once agreed guest numbers or food requirements are met. Friday and Saturday nights, Christmas dates and other high-demand periods can also have different terms. When comparing venues, it is important to consider the total cost of the event rather than the room hire fee alone.

Can I hire a function room in Dublin with a private bar?

Yes. Many function rooms in Dublin have their own private bar, although this isn't standard at every venue. A private bar can be particularly useful for company parties, Christmas parties and larger celebrations because guests can remain within the function space rather than using the venue's main bar. Always check whether the bar is exclusively for your guests and whether any minimum-spend conditions apply. If you're planning a larger meeting, presentation or delegate event, our Conference Venues in Dublin guide covers venues designed specifically for conferences and larger corporate gatherings.

Which function rooms in Dublin are suitable for 100 people?

There are plenty of function rooms in Dublin suitable for around 100 guests, including Lost Lane's Library, The Bridge 1859 when its two rooms are combined, The Goat's Anvil Room and larger configurations at The Harcourt Bar. The right choice will depend on whether your 100 guests will be seated or standing and how much space is required for entertainment, a dance floor, AV or food service.

Do function rooms in Dublin require a minimum spend?

Some do, particularly for exclusive use on popular nights. A minimum spend normally means your group must spend an agreed amount on food and drinks rather than paying a separate room hire fee. The amount can vary depending on the venue, date, guest numbers and time of year, so we recommend checking the full terms before comparing one function room with another.

Can I hire a function room for a corporate event in Dublin?

Yes. Dublin has function rooms suitable for corporate presentations, networking events, product launches, company parties, client entertainment and private dinners. For corporate events, we normally look beyond capacity and consider AV facilities, room layout, privacy, location, food and drink, accessibility and whether the space can comfortably accommodate the different stages of the event.

Which function rooms in Dublin have AV facilities?

Several of the function rooms in this guide offer AV facilities. These include the Iveagh Suite at Iveagh Garden Hotel, O'Neill's Merrion Row Green Room, The Harcourt Bar's function spaces and Merchant's Arch Private Function Room. Facilities vary from screens and projectors to microphones, PA systems and connections for presentations, so the exact AV requirements should be confirmed before booking. If the venue doesn't provide everything your event requires, our Corporate Party Hire service can also help with additional equipment, staging, lighting and event setup.

How far in advance should I book a function room in Dublin?

For a Friday or Saturday night, a large company event or a Christmas party, it is worth starting the search as early as possible, particularly if your date is fixed. Smaller events and midweek functions can sometimes offer greater flexibility. Guest numbers, location and the type of room you need will also affect how many suitable options are available.

Can Find a Venue help me find a function room in Dublin?

Yes. Find a Venue has been sourcing venues in Dublin for more than 15 years. Please tell us your preferred date, guest numbers, budget, and what you're planning, and we can identify and compare function rooms that suit your event's requirements.

Whether you're organising a corporate event, Christmas party, private celebration, networking event or company dinner, send us your brief and we'll help you find the right venue.
