First things first, GET THE BRISKET, explanation below.
I'm a big fan of Condado. IMO, it's a mix between fast food tacos and gourmet tacos. There's a ton of great options. I like building my own tacos and adding as much as I'd like. I highly recommend the brisket, it's extremely flavorful and not dry.
Service is good, food comes out fast, and it's cheap compared to other tacos joints.
