A+ for authenticity, and excellent food too. The signature dish are the goat tacos, which I love. Make sure to use lots of lime and dipping sauce. The tortas look good, but I can’t bring myself to pass up the tacos. DC in the last few years has snagged some quite good Mexican places, but this is the suburbs catching up. Not a super-broad menu, but they do things right. Recommended.
