El Centro D.F. is one of Richard Sandoval’s restaurants, which includes 19 restaurants, like Zengo, Masa 14, and Ambar.
We started out the evening with a $4.00 happy-hour margarita in the open-air (but covered) bar upstairs. The happy hour guacamole and house made chips is a great starter to go with the El Centro margarita as well.
For dinner I ordered up one of the Grilled Nopal taco option, which came with three tacos made with cactus, vegetables, chayote, queso fresco, salsa roja, rice, and beans.
If you are looking for Mexican near 14th st/U Street this is worth dropping by for, especially if you want to take advantage of the drinks/tacos during their rooftop happy hour.
