It's all about the music. This review is for the club/lounge, not the restaurant. Me and 3 gf's came out of Peepshow and there was someone handing out wristbands for Koi.
I'm not super impressed with this place, but the music was actually pretty good and having the girls there made it even more fun. There were enough oval couches to take a breather from dancing and lots of people watching.
$20 wristband gets you a pink cup with an open bar for the night. Drinks were okay and not too strong that it would knock you out after half a pink plastic cup.
It was convenient for us to enjoy the rest of the night here, since we were staying at Planet Hollywood.
