Can you stand at the bar during a show? Is there a place to dance during a show?

Yes you can stand by the bar but there's a distance from the stage. The floor is open but can get crowded leaving little room for dancing.

Depends on what show it is. I attended all dance, no seating at all.

Two thirds of the space is seated, one third is general assembly/standing floor space. At the show I attended on 11/12, people stood by the bar throughout the night.
