Probably the least expensive, delicious Mexican food in Watsonville and that says a lot! I don't think they have anything on the menu over $10. It's located in an old fast food restaurant and is pretty bare bones--no atmosphere just good food at low prices. Campesinos come here after work and people line up on weekends to take home pots of menudo, pozole and birria.
If you've never been in a quality Mexican supermarket, walk across the street to the Santa Fe Market and do some browsing.
