I haven't been here in years, but i had some great memories here. I saw The Pussy Cat Dolls here, met Sway with Mary F and spent the entire night with him, so much fun! The club is HUGE, but I heard XS is bigger than Pure. It's very hard to get in here, you need to coordinate girl vs guy ratio and pay the bouncers in order for you to get in! Once you're in, you'll have a great time. Make friends with people that have VIP tables.
Good luck!
