Ichibantei hosts group dinners and private events for 12 to 65 guests in the East Village, New York, and its third-floor space, Studio Hundred, takes up to 130 guests. The Japanese restaurant at 100 3rd Avenue, a short walk from Union Square and Astor Place, offers a semi-private upstairs floor that can be reserved in full for a private event.
Seminars and company events
Corporate dinners and client entertainment come first on the restaurant's list of uses. Office holiday parties, year-end dinners, cocktail receptions and full-restaurant buyouts are also offered. Groups of 12 or more are served one of two course menus built around Japanese comfort food: donburi, katsu, curry and teishoku sets. Vegan and vegetarian versions are available on request, including a vegan katsu curry.
Audiovisual equipment can often be arranged on request. The restaurant recommends booking ahead for course menus and full buyouts, especially on weekends. Organisers send the group size, preferred course, date and occasion, and the restaurant usually replies within 24 hours.
Rooms and capacities
The restaurant has no enclosed private room. The second floor is a semi-private mezzanine overlooking the main dining room, reached by stairs, and it seats up to 25 guests. A ground-floor buyout fits up to 40 guests, and a full-restaurant buyout fits up to 65. Reserving the entire upstairs floor gives a fully private setting, best suited to parties of about 20 or more.
For a standing party, Studio Hundred is the third-floor event space. It hosts up to 130 guests with an open bar and stays open until 4 AM. The restaurant itself is open until 3 AM every night, so a dinner can continue into an after-party, and live performances are possible.
Tables for up to 12 guests are booked directly through the restaurant's online reservation page. Larger parties go through the group dining inquiry form or by email.
Catering
Catering is handled in-house by the restaurant kitchen and bar. The group menus are prix-fixe and served to the whole table, with drinks from the bar. The restaurant also publishes a guide to vegan, vegetarian and gluten-free dining for guests with dietary needs.
History and setting
The restaurant presents itself as an intimate Japanese izakaya serving home-style set meals, with a bar and late-night hours. It sits on 3rd Avenue at 13th Street, near Union Square, Astor Place and St. Marks Place. Its private events page also offers a Japanese-language path for year-end and New Year parties.
Birthday dinners, graduations and rehearsal dinners are listed alongside corporate bookings. Weddings are not offered as a service on the page.
