My best friend kept telling me how great XS night club is and that he thinks I should check it out even though I don't enjoy clubbing, so i took his advice and took my GF's to XS for my friend's bachelorette party weekend. We went on a Friday night. We were the first ones in the club and they were playing house music for a few hours. They didn't start playing good music that my friend's would dance to until midnight.
As for a non-clubbing person, I thought the place looked nice, different from what I've seen in Vegas night clubs. It's nice that it's outdoors, to get some kind of fresh air. =p
Their drinks, well it's Vegas - so 6 lemon drop shots at 10PM was $75 out of my pocket. Bottle service is $500, i guess that's not bad compare to what I've heard - they can range up to $1,000!!
