The Ellicott City location and the Downtown Annapolis locations have a private room
No private room but I did have a birthday party there for my dad a few years ago and it was no more than 12 or 13 of us. The staff was very accommodating. They helped push tables together and very attentive as usual.
They don't have a private room.
The one I visited did not have a private group room. I suggest you contact the store nearest you to discuss the matter. I do know they cater for groups .
I didnt see any private room when i was there... And for what its worth ive never seen any Mission with a private room
