Back when I went (over a year ago,) Pure was excellent. The white room, the rooftop, the Pussy Cat Doll lounge were all great. The drinks were pricey obviously, but the music and crowd were good. Cream of the crop!
I've heard its kind of given way to the newer clubs. My friend who used to love this place doesn't want to go on our next trip. If that's true, too bad, but it was a great time when I came.
