It is a small showroom: capacity capped clearly at under 1000.
It has a reasonably decent soundsystem. I always protect my priceless hearing with "true-to-the-ear" hearing plugs. It can get pretty loud in here for a rock show, especially when considering how small the room is, so protect your hearing.

Box office is fast to distribute tickets; ushers are quick to seat you; and, for the shows where people want to stand up near the stage, it is permitted. Plenty of space in between aisles: unless that is, you are Manute Bol.
Restrooms are outside of the venue, to your immediate left, upon exit on the Southern-most door (in the Keno area).
There is a bar, but I have never partaken. Don't drink and drive. - E
