Just tried Catrin, which recently opened on East 7th Street, just north of Church Avenue. We started out with a simple chips and guac, which was a really pleasant surprise: flavorful, nicely-textured guac and chips that were mildly warmed. We then got an order of shrimp tacos with a chipotle mayo, which was very nice, and quesadillas, one with huitlacoche and one with chicharrones. I thought that the huitlacoche quesadilla was alright, the chicharrones quesadilla better. But the surprise of the meal was a Mexican-style hamburger, made with chorizo and garnished with Oaxacan cheese and avocado. I would definitely return to this place, particularly as the other taco options look good as well.
