Reservations may be made by phone, by email, or online via OpenTable.com.

Dinner Reservations made through Open Table automatically get placed in the Soirée Dining Room, unless that room is fully committed with a private event, in which case, your reservation will be placed in the Monday Club and a message will appear letting you know as you make your reservations on Open Table.

If you want to reserve a table in the Monday Club Bar, or if you try to make a reservation through OpenTable.com and fail to get the time or date you want, be sure to give us a call to make sure we cannot accommodate you at that time/date (often we will block times to control reservations).
