I may be risking food poisoning, but this middle-aged Chicana and her operation looked pretty clean and my curiosity about homecooked Mexican food got the better of me. And I had already eaten a Thai lunch.
Come what may, the food was very good. A big plate of "Barbecued" chicken in a pungent red chili paste with lots of dried bay leaves, penne in a creamy tomato sauce topped with a mound of dry cheese (cotijo?), a thin fiery tomatillo salsa and commercial corn tortillas. Everything tasted fresh and quite good.
She is a regular at this spot and told me that last week she had a shrimp/octopus/fish ceviche and tomorrow vegetarian quesadillas. I just happened to park behind her today!
