Private Dining and Events in Midtown Manhattan

Rooms that keep secrets.

Host your next private dinner at Sei Less in Midtown Manhattan. From corporate gatherings to birthdays and special celebrations, our team will help you choose a space and menu for your occasion. Send your date and guest count to discuss availability.

Event Inquiries

Tell us the occasion. We’ll handle the rest.

A group dinner shares the restaurant setting; a private room offers a separate event space; a full buyout reserves the venue for your event. Our team will help with the space, menu and availability.

For a regular table, book on Resy or OpenTable. For groups of 7 or more, or a private event, use this inquiry form. It accepts requests from 5 guests; that form minimum is not a private-room capacity or a guarantee of availability.

◆Flexible spaces — private rooms, semi-private booths, a lounge and full buyouts on request.
◆Your layout — seated dinners, standing events and full buyouts have different capacities; the team will confirm the right fit.
◆Human confirmation — room, layout, menu, pricing and availability come from the events team.

Private dining questions

A clear plan for your group.

From your first inquiry to the signed agreement, the events team helps confirm the room, menu and arrangements for your occasion.

How do I book a group dinner or private room?

Groups of 7 or more should use the event inquiry form and dine from a family-style prix-fixe menu. Private rooms generally require a guarantee of at least 20 guests. Smaller groups generally use the main dining room; the events team confirms the space and arrangement for your party.

How many guests can a private room accommodate?

One private-room option seats approximately 43 guests, depending on layout and service. This describes that room option, not the entire restaurant or a full buyout. Share your seated or standing format and guest count with the team to confirm the specific room, layout and capacity.

When is my event confirmed?

Your event is confirmed once the contract is signed and the required deposit has been successfully processed. An inquiry, proposal or unsigned contract does not secure the booking. Any courtesy hold must be confirmed in writing by the events team and may expire.

How do deposits and cancellation terms work?

The deposit amount is set out in your proposal or contract and is credited toward the final bill. It is non-refundable unless the written contract says otherwise. Review your agreement for cancellation deadlines, other charges and the guaranteed guest count before signing.

Can we plan music, a presentation or personalized menus?

Private rooms have music capabilities and smart TVs. Coordinate presentations, playlists, files and adapters with the events team, and confirm the equipment and any technical fees for your room. Personalized menus may be available with advance notice and approved artwork.

Can we bring decorations or an outside photographer?

Decorations and setup arrangements require advance approval from the events team. Sei Less does not allow outside photographers or videographers. Ask the team about any other photography needs, and confirm approved vendors, delivery and removal times before making arrangements.
