Now this is a great taco place. Just a block off of U street it's a great place to stop for a bite before a show or while your drinking. It's feels incredibly authentic and the food is absolutely delicious. 3 tacos for $9 is about standard in DC and is far more worth it here. They use corn tortillas and are inherently gluten free. I tried the chicken, steak, and al pastor tacos. They were excellent and I wish I had ordered more. The guac is fresh made and variably spicy, depending on how you like it. Their brick-and-mortar location is just a little house so it feels incredibly comfortable and is very inviting. I'll certainly be going back in time for my next show at Black Cat if not sooner. I definitely recommend everyone. tl;dr - delicious authentic tacos. Try the steak, chicken, al pastor, and guac. Very inviting and friendly staff. I will definitely go again.
