I wasn't on maps app when I posted so if this is a duplicate I apologize. Do you have a separate area for a 15-20 family gathering? Can it be reserved on a saturday afternoon?

Yes there is a room in the back.

Yes there is a large area in a separate room

Yes there is a big room in the back for large groups and can be reserved

I've used the room by the bathrooms for a large group. Call and ask

They do have a side room that would hold your group.

Can hold that many not sure about a Saturday reservation

Call. They've got an area I would assume you could reserve.
