After hours?...Hmm...more like no man's ville. Went on a Friday night with about 15 people, mostly ladies. Got a free limo pick up which was cool. They said free entry but really we had to pay $20 for 2 drink coupons to get in "free"...I guess it was a bargain in hindsight. We walked in and the place was empty...it stayed that way. We quickly realized it is attached to a strip club, Crazy Horse...tha is its saving grace because not only is the music waaaay better but the place was packed. So what POSH lacks in people, music, and entertainment...Crazy Horse makes up for it. Both clubs are connected so entry into one gives you access to the other. Even if female strippers aren't your thing...the playlist and energy are better than whatever is going on at POSH :/
I honestly would not return for an after hours experience, I would chose Drai's or Artisan but I would stop by Crazy Horse again :)
