It's not because the authentic tacos served at this unassuming storefront cantina are inexpensive (they're $1.50 each) or that the selection — beef tongue, spicy chorizo, fish, fried fish, carne asada, poblano chile and cheese, chicken — is so interesting that El Camino Real is such a mecca for taco lovers. It's the whole taqueria experience. While customers wait, one of the employees mixes the corn masa by hand, puts the mixture into a steel roller, and tosses it right on the grill where a cook is grilling the chopped meats that are then folded into the warm corn tortilla. The tacos are presented in plastic baskets with little bowls of fragrant chopped cilantro, onion, pico de gallo, and a punchy house salsa. Lots of other dishes are on the menu here, including a fine chile relleno, but the tacos are too tantalizing to pass up.
