For private dining events, split checks for payment is not an option for the main dining agreement. At the time of contracting the room, the main contact provides the credit card that will be used for deposit and event final payment. If at the end of event, a different form of payment is provided, this is fine; however, it is a lump sum payment, not individual checks.
Cash Bar -- for this selection of bar service, each guest ordering cocktails will have a separate check and their beverages not applied to the main tab nor food & beverage minimum.
