Much like Toad's place or Lupos... a big wide room with a stage and a bar.
been there a couple times and taped each time. Obviously this would depend on the people there, but it's been chatty as hell every time I've been there and I've yet to pull a tape that I would call good. They were all listenable, but I wouldn't call them 'good'.
No board patches... the owner is very anal about letting the sound guy give a patch even if the band is cool with it. If it's not too crowded I'd setup in the middle of the room ~20' back from the speakers. Otherwise you're pretty much forced to tape from the side of the entrance into the place which forces everyone who wants to get a drink to walk buy your rig (probably the biggest reason why the tapes are all chatty).
