I've recently frequented a taco truck on the corner of LaBrea and Olympic (It's there at night on the weekends) that parks in an auto mechanic parking lot. Very simple menu -- no chicken, no tortas/tlayudas as far as I know. Good green and red salsas, and the best Al Pastor I've had in this city (better than La Oaxaquena, El Taurino). Carne Asada is good as well. Jalisco-style recipes. Easier access than Venice and Rose for those of us east of Robertson.
