This is an outstanding taqueria. The tacos are large and delicious. When we went, the place was packed and we had a 20 minute. No problem, on Tuesdays, there are margarita specials, and Barrio has some really good margarita offerings, which are served in mason jars.
Ordering is done on a pre-printed tablet like you find in sushi bars. You can pick from a variety of a la carte tacos, or you can build your own. They have about a half dozen sides to go with your tacos.
I ordered 3 tacos and 2 sides. I was stuffed, and I am not a small man. The servers were friendly and engaging. The decor was Mexican Death (skeletons). The atmosphere was boisterous, and everyone was having a good time.
I'll be going back.
