Overall a good restaurant, with nice outdoor seating, but it is the two blue corn dishes that really make it. The huitlacoche quesadillas and the blue corn tamales are A+. Go for those, and for the Oaxacan chocolate sorbet at dessert. The rest is good enough, the beets would be another dish you could try. And note my two top picks are nominally vegetarian, though I cannot promise that animal products never appear in the dish.
