LOUD, scantly clad girls dancing on poles in the back (doesn't bother me but causes the crowd to be comprised of the next complaint), gross, drunk old men drooling underneath the dancing girls, impossible to get a drink on a busy night, and if you do manage to get a drink it will be promptly spilled everywhere as ten people try to get a spot at the bar.
The best time I've ever had at the bar is LEAVING.
