I would give this place three stars if just comparing it to other nearby venues. The drinks are standard (the selection is perhaps a bit lacking, although the bartenders are good), but the (metaphorical) atmosphere is quite chill.
The (actual) atmosphere is quite smoky, though, so subtract a star if you (like me) can't stand tobacco smoke (hookah smoke isn't nearly so noxious, but people bring cigarettes and cigars as well). I left that out of my rating since it's a matter of personal taste.
