Fresh, homemade tortillas in the SGV?
Haven't been in a while, but one of my favorites is Tortilleria La Azteca in Monterey Park (right across the street from Gallos Grill, rip). Kick ass corn and flour tortillas, hand made and hand formed. Really, really excellent.
For some reason, I'm having trouble getting the place link to work, so here's the address the old school way:
Tortilleria La Azteca
4538 Cesar E. Chavez Ave.
Los Angeles, CA 90022
