La Bamba is a litle Taqueria in Mountain View that serves pupusas. Pupusas are Salvadoran pork, bean, and cheese stuffed masa flatbread with curtido and a light, watery tomato salsa. Curtido is a lightly fermented cabbage slaw with red chillies.
On yelp people have written that the burritos at La Bamba are some of the best in the South Bay. I have to say, go with the Pupusas!
Parking is slim and there aren’t any tables inside but one so you sit at a low counter with chairs around the periphery of the Taqueria. Cheap and tasty!
