Private dining near Union Square: published capacities
Seven venues near Union Square, sorted by the seated capacity each one prints, and how to get the minimum that almost none of them publish.
Sourcing a room near Union Square usually starts with a spreadsheet row that reads private dining nyc, 30 guests, first week of November, and ends with seven inquiry forms. The useful sorting here is not by cuisine. It is by which venues publish a capacity you can plan against and which ones make you submit a form to learn anything at all. Below are seven venues within roughly a ten minute walk of the square, ordered by the largest seated number each one prints on its own site. One of them publishes per person package pricing. The rest publish no food and beverage minimum anywhere, which is the most important thing to know before you start calling.
At a glance
Sorted by published seated capacity in a dedicated private room, smallest first.
Union Square Cafe, The Alcove: 10 seated. Il Fiorista, Chef’s Table: 12 seated. Gramercy Tavern, Private Dining Room: 20 seated. Casa Mono’s sister room Bar Jamon: 22 seated. Il Fiorista, Flower Room and Private Dining Room: 24 seated. Scarpetta, Private Dining Room: 30 seated. Union Square Cafe, Park and Irving Room: 40 seated. Pete’s Tavern, Private Speakeasy Room: 44 seated. For full buyouts the range runs from 40 seated at Casa Mono to 120 at Gramercy Tavern.
The number nobody prints
Of every venue below, exactly one publishes what an event will cost per head. Pete’s Tavern lists four package prices. Everyone else routes you to an inquiry form or an events email, which means the minimum is set per date, per room and per season, and you will not find it before you make contact.
This is normal and it is not evasion. Minimums move with the calendar, and a Tuesday in February is a different conversation from the second week of December. But it does mean that a shortlist built from published capacities alone is only half a shortlist. When you call, ask three things in this order: the food and beverage minimum for your specific date, whether tax and gratuity sit inside or outside that number, and what happens to the minimum if your count drops. The third question is the one people forget, and it is the one that costs money.
Private dining near Union Square, by published capacity
Union Square Cafe, 101 East 19th Street
The most granular published set on this list. The Alcove seats 10. The Park and Irving Room seats 40, or 45 standing. A full buyout takes 100 seated and 200 standing. Having a genuine 10 seater matters more than it sounds, because most rooms in this neighborhood bottom out around 20 and a party of a dozen ends up rattling around a space built for twice that. No minimums are printed. The reservations line is (212) 243-4020.
Worth asking: whether the Alcove is enclosed or open to the room, since the site does not say.
Gramercy Tavern, 42 East 20th Street
One private dining room seating up to 20 for lunch and dinner daily, around a single table, and a full restaurant buyout at 120 seated, which is the largest buyout on this list. No minimum is published, and neither is a direct phone number or email for events: inquiries go through a form, so build a day into your timeline for the reply.
Worth asking: whether the buyout number of 120 includes the Tavern room, the dining room, or both.
Pete’s Tavern, 129 East 18th Street at Irving Place
The one venue here that shows its pricing. The Private Speakeasy Room takes 44 seated across three straight tables, or 32 in a U shape. For a buffet it holds 45 with 30 seated. For a cocktail reception it takes 50 with 30 seated, or 65 with no seating at all. Package prices are printed per person before 8.875% tax and 20% gratuity: standard passed hors d’oeuvres at $38, premium at $57, buffet with passed hors d’oeuvres at $80, and a family style sit down dinner at $85.
The terms are printed too, which is rarer than it should be. A 20% non refundable deposit is due at booking, events run to a three hour maximum with departure times strictly enforced, and the final count is due four days ahead. The site states that the minimum spend varies by date and time and is set by the banquet manager. Contact manager@petestavern.com or 212-473-7676.
Worth asking: nothing, relatively speaking. Start here if you need a number this week.
The ABC rooms, 38 East 19th Street
abcV and ABC Cocina share a building and an events team. abcV buys out at 75 seated or 120 for a cocktail reception. ABC Cocina buys out at 90 seated or 150 cocktail. Neither publishes a separate private room, so the model here is take the whole restaurant or book a large table.
The large table thresholds are published and unusually specific. At abcV, parties between 11 and 24 are accommodated, with 11 to 14 booking directly and anything larger submitting a request. At ABC Cocina the band is 11 to 34, with 11 to 18 booking directly. Events run through events@jean-georges.com or 212-358-0688.
Worth asking: both sites have displayed a notice about a short closure for a refresh with no year printed on it. Confirm by phone that you are booking against a live calendar.
Casa Mono and Bar Jamon, 52 Irving Place
Casa Mono’s events page publishes 40 seated and 55 standing. Bar Jamon next door takes 22 seated or 33 standing, and the two sit side by side on Irving Place at 17th Street, just east of Union Square. Figures for the standing capacity have appeared inconsistently across the site, so get that one confirmed rather than planning to it. Phone 212 253 2773, or events@casamononyc.com.
Worth asking: whether the two rooms can be taken together, which would be the most interesting configuration on this list and is not addressed anywhere on the site.
Il Fiorista, 17 West 26th Street
Further north in NoMad, but it publishes more detail than most. The Flower Room takes up to 24 seated or 40 standing. A separate private dining room is listed at 24. The Chef’s Table seats up to 12 and runs a three or four course menu. A full buyout takes up to 95. The restaurant also offers private classes covering floral design, pasta making and mixology, which is a genuinely different answer if your brief is a team offsite rather than a dinner.
Worth asking: inquiries route through a booking platform rather than a named contact, so expect a slower first reply.
Scarpetta, 88 Madison Avenue
The largest set of options here, though the detail lives on its operator’s events site rather than the restaurant’s own. The main dining room takes 115 seated or 200 standing. The private dining room, on the restaurant level, seats 30. The Studio Room takes 50 at a long table or 80 standing, and the Library Room 20 or 30 standing, both on the lower level. The Madison Room is a 2,200 square foot gala space listed from 80 to 180 seated depending on the configuration, or 250 standing. Events run through (212) 532-4100.
Worth asking: which of these rooms are in the restaurant and which are below it, since the distinction affects service and load in times.
The venues that make you ask
Isabelle’s Osteria at 245 Park Avenue South describes a private dining room on its site but publishes no capacity for it, no minimum, and no room name. What the site does print is that the restaurant seats 150 overall, which tells you the building is large enough to be worth a call and nothing about the private room itself.
It is worth the inquiry for a specific brief: a dinner in Gramercy Park where you want contemporary Italian rather than steak or tasting menu formality, and where a bar area matters because guests will arrive across a 40 minute window. The verified detail that makes it useful for that shape of event is the weekday Aperitivo Hour, which runs 2 to 6PM at the bar and gives early arrivals somewhere to be. To get the numbers, learn about private events at Isabelle’s through the inquiry form, or call (212) 388-1145 and ask for the capacity and the minimum on your date in the same breath.
If your event is really a large dinner rather than a private hire, the practical differences are covered in this look at what to check before booking a group table near Union Square. And if guests are arriving from a show or a conference, timing matters more than the room, which is the subject of this guide to eating around a Union Square event.
Where to go from a shortlist
Once you have three venues that fit the headcount, the work is the questions rather than the rooms. Our guide to how to plan a private dinner in NYC sets out the sequence from headcount to contract, and the same comparison method applied to the blocks north of here is in how to compare private rooms in Gramercy.
Two variations worth reading separately. If the booking is a midday one, the constraints change completely and are covered in booking a business lunch near Union Square. If the date is fixed by a wedding, see choosing a rehearsal dinner restaurant, where several of the rooms above appear again grouped by guest count.
Frequently Asked Question
How far ahead do I need to book a private room near Union Square?
For a weekday dinner outside the holidays, four to six weeks is usually comfortable. The pressure points are late November through mid December, when corporate calendars collide and the good rooms go months out, and the first two weeks of June for graduations. The other constraint is less obvious: venues with a single private room, which is most of this list, can only host one event a night, so a room that seats exactly your headcount may be unavailable on your date even though the restaurant has tables. Build a shortlist of three venues rather than one, get the minimum for your date from each, and hold your preferred date with a deposit as soon as the numbers work.
Before you call
Capacities on this page were read from each venue’s own site in early August 2026, except Scarpetta’s, which are published on its operator’s events site. Rooms get reconfigured and capacities change with them. Confirm the number for your date and get the minimum in writing before you commit to anything.
