The one outside Caesars? (There may be another one, I can't remember).
Its a pretty good place to hang out with friends, most of the times I've gone there were during the day though before we found other things to do at night. Me and my friends usually stop there when we can though, its a pretty good time.
Funny story there though, we went there for my friends bachelor party and kept feeding him drinks. He was pretty drunk, but not THAT drunk, at least visibly, when the bartender flagged him and said he couldnt have any more drinks. A few minutes later we all got thrown out for giving him more drinks, but in any case, we all walk out under our own power, and literally within 5 minutes of leaving the bar, my friend who was flagged passes out in a bush and we have to drag him back to the hotel. Thats a skilled bartender when he can spot that coming and flag someone like that

Anyway maybe it wasn't that funny, you had to be there. Haha.
