I went here briefly with a friend the last time I was in Sin City a few weeks ago.
We had gone to dinner nearby and decided to give it a try. We weren't on the list so we waited with the non bottle service commoners. The line goes around the escalators and wasn't too bad.
Once inside we went upstairs to the club area (the restaurant still had dining patrons).
The dj played some good music but we didn't stay long.
The scenery of the people was washed up but the ambiance was cool. The bathrooms are individual rooms not stalls in a larger room. The door fogs up when you lock it, much like the restrooms at a place called Bar 89 in SoHo, NYC.
I would go back but maybe start earlier. I think we were full from our dinner and we had also drank an entire bottle of vodka.
We left shortly after and my friend twisted her ankle. Fail. Ha.
