I attended a fundraiser event held here on a Tuesday night. It is much nicer and cozier inside than it looks from the storefront on 17th! Not a fancy place, but since its fairly new (I think they opened Sept. 2013), you can tell the renovations turned out really well for them - they did the best they could with the long and narrow space.
Food was quite good - I don't normally expect food at these types of events to be that tasty but I was pleasantly surprised. Pricing and portion size for a quesadilla seems on par with a restaurant like Earls or Moxies but tasted way better - try the chicken mole or chorizo. Salsa and guac are good. (Burrito is also quite large - a guy at our table couldn't even finish his!) I think they forgot the alcohol in my margarita but it was a free drink ticket so I didn't bother complaining. Dessert was churros, which were delicious! The chocolate dipping sauce kind of tasted like nesquick but fortunately the strawberry sauce tasted like real fruit! Overall, I am not a connoisseur of Mexican food so can't speak for how authentic everything was.
There was some live music during parts of the event; the performer played the guitar and sang in Spanish. I believe he is a regular there for certain nights a week and it helped add to the atmosphere for the event. Service was also friendly and fairly quick given that it was a full house!
I would definitely go back and give the other menu items a try!
