Tortilla chips topped with braised pork, black beans, cheese, salsa fresca, guacamole and sour cream.
La Tortilla, San Francisco

So the food here isn’t the best Mexican food you’re gonna eat in the city but it’s convenient, fast, affordable, and they serve large portions.  Their al pastor has decent flavor and is sufficiently tender.  Everything else is pretty standard, but I do like their salsa bar. I tend to drown everything in extra salsa, hehe!
