Private room in DC or Virginia for a graduation party

[Anonymous]

My stepdaughter is graduating from college. Between friends and family, thinking she’d like to celebrate with about 30 people. What would be a fun venue for something like this that is budget conscious. We have done similar events at Courthaus Social in Courthouse. But we are looking for a change. welcome any ideas, prefer not to pay a high fee to reserve the room, would prefer to spend the money on a food/beverage minimum. We live in Arlington, so something convenient that location would be great. Some folks will be staying in Ballston.
