Yummy, but pretentious. I've only been on weekends, but the wait is always super long. We waited over 3 hours (on a Saturday night, to their credit) for 3 people, and then were seated at the bar..
Just discovered that Atlas (downstairs part of the Row house) is BYOF (what?!), and the awesome bartender there gave us the grand idea of ordering takeout and eating there..definitely the better experience!
Queso is my favorite from anywhere, but I like Doce Taquerita's tacos way better (and they're half the price, with like a 5 minute wait time).
