I second Tacos al Gordo. Best street-style tacos you can get in the USA. Chula Vista has some AMAZING Mexican food. And CHEAP too. Unfortunately, most gringos are afraid of going down there, but its their loss because the food is to die for. Agave Grill has some outstanding seafood, not like you’ve ever had before. We’re talking Sinaloa style Mexican. Tacos, burritos, etc are good, but they only represent northern Mexico and don’t cover all that Mexican food has to offer. Creamy, chesey sauces — almost more Italian than what most people think of Mexican. There are also some amazing torta shops all along Broadway in Chula Vista. Elotes and horchata FTW.
