Went here for the second time last night to a GBC student-run event, Musicology. The drinks aren't a deal, and there's a $25 minimum for using your credit card at the bar (Which is crazy... who spends that much at once?)
Getting to the bathroom is a bit of a hassle as you cross paths with the performers, and the stairway always seemed full.
Besides the above, it was a great venue. Really nice atmosphere and definitely somewhere I'd return to.
