Yeah it is just a mingle sort of situation. You can sit if you want or stand up and dance. Fun atmosphere.
You can sit on the patio or the booths, maybe upstairs too. Regarding reservations, I'd say call them or email them.
The only place we could sit was upstairs or by the entrance. Still fun. It was standing room only that night. The front booths were reserved.
It depends on the night and it depends on if it is a concert. But usually you just need to call ahead of time to reserve.
