I always have a great time at this place when I'm in Arizona. Doormen are cool, security guys can be tools (sometimes they have to be), and the female staff is very hot, but they do know it. I've been there on many occasions, and lets just say they aren't the friendliest. I wonder how the got the job...Hmm I wouldn't say they were very customer service oriented. The DJs and Bands have always been amazing.
Highly recommend going on Saturday night. Patrons are friendly, women are very easy to talk to. Sunday is an industry night which comes with the Industry crowd (could be good or bad). Metalhead or Rock Lobster are both good bands though so if you've got company (aka date or entourage) it doesn't matter which night you go.
