I was invited to a party with these international exchange students and it was a great night. The music is decent and there are 2 spacious floors. The environment is quite dark and intimate and the music isn't overly loud to the point where you have to shout.
There is no bar service so one of the downfalls is that you need to wait till someone comes to your table.
BTW, don't order nachos - they suck. My homemade ones are much better. Just go for drinks.
So if you don't mind walking through a back alley - it isn't that sketchy, really - it's a great place to wind down.
