A caravan parked at the side of an old carwash by Davis High School, El Escorpion serves up delicious burritos, tacos, tortas, etc. You choose the meat (or no meat). The owners are quietly friendly, so sweet. Lengua (tongue) costs more than other fillings, but it is exceptional. The marinated pork (adovada) is very popular. You order at the window; there is no seating.
