A really fantastic taco. Efficient & delicious. I've eaten at 3 of their locations. The food here was good, but not quite on par with the El Cajon location (now closed).
I'll say this, even a mediocre Tacos el Gordo taco bests 99% of another taco. They're my favorite taco, and I'm nearly sure they'll be yours. I honestly wouldn't miss the chance to eat here. It's an authentic taste of real Tijuana tacos, without the fuss (or beheading) of a boarder crossing.
I highly recommend you hit them up, for what's likely to be the best taco you've ever had. Start with 4... but be ready for 6+... bring your stretchy pants people.
