Ah, tacos. Our LA Galaxy supporter's group has hired a taco cart on many occasions. The tortillas are small soft corn, maybe 5 inches in diameter. Fillings are carne asada (steak), pollo (chicken), or carnitas (pork) most commonly. Top with some chopped onions and cilantro and some hot salsa. Mmm...
I may be of Japanese descent, but growing up in LA, I've eaten more tacos than sushi over my lifetime.
Heatmeister, if you can get small corn tortillas, those are the authentic ones. If you ever make it out to LA, I'll hook you up with some authentic tacos.
Oh, and TX Bill, those JITB tacos are the most awesome late night food post pub crawl. After bacon wrapped hot dogs, that is.
