I believe it's officially 850 but typically capped at 800.
800 with 150 seats. But its a great, intimate venue - tiered for a good view wherever you stand, even in the back at the bar is a good show. Also a balcony for the aerial view (this is where the chairs are).
I actually did a search for this and couldn't find a definitive answer. I think 600 may be a max, but - it is standing room only, so maybe not. It is 40' x 120' and is a converted movie theatre. So 600 ppl in a 480sq ft, seems like a lot too me. There is room for another 50 or so ppl in the balcony. Certainly not 800 ppl.
Its neither too big nor too small... I was there for a musical concert some time back. Without any seats i would so it can accomodate around 600-800 people pretty comfortably.
