Tacos El Gordo serves a variety of mini-sized tacos made-to-order, as well as mulitas and sopes. Many of the meats are "exotic" to some, but San Diegans have become accustomed to seeing cow brains and pig esophagus on the menu, and in fact, the fifth quarter is hardly what has earned El Gordo its reputation. In my opinion, the standout options here are of a less intimidating variety.
A lot of trends have hit the local taco scene over the last ten or fifteen years, from the initial fish taco boom to the spread of pollo asado, the ascendance of carnitas and, more recently, the dawn of the Korean barbecue taco truck. San Diego has room for all these kinds of taco shops, and more. While El Gordo may or may not have spearheaded the "Tijuana taco" phenomenon on this side of the SD/TJ metropolitan area, with locations not only in Chula Vista but also Mission beach and even Temecula, the fat man has certainly earned himself a piece of the action.
