No kid, casual, pre-concert suggestions

Ok. Going to a concert at Northerly Island. Want somewhere casual to go, no reservations, also importantly no kids with us (fine with kids being there, obviously). Kind of whatever the cool spot is that would be fun to go to getting out of our usual rhythm. Bucktown/Logan or I suppose downtown, but preference for the former so we can easily uber over there. Anything new opened up that fit that vibe? Something like Omarcitos is probably the closest I've gotten to, just a little bit annoyingly in the opposite direction of where we're going, but may still check it out.
