I've been here twice, but am writing a review for my most recent trip to PURE, last Saturday.
Yikes - $8 for a tiny-ass bottle of Fiji water? I don't THINK so! And they won't serve you tap or any other kind of water, either, so make sure you don't overdo it here with the liquor at PURE.
Luckily, we were able to crash a bachelor party in one of the reserved red velvet booths, where they had plenty of Grey Goose and bottled Fiji to go around, but if you aren't as lucky as we were, I'd say save your money and try a cooler place...
The patio on the top is nice, though. You get a great view of the strip.
