Thanks for the recs. Made the drive up and back last weekend:
Stopped at House of Pendragon in Fresno on the way up for beer (was underwhelmed, found stuff to be fine but not any better than that) and ate at the destination.
Stopped on the way back at Loncheria Otro Rollo for Jalisco-style tortas ahogadas and lonches. Not quick and not ideal for eating in the car, but it was a really enjoyable stop; pork was juicy and great, salsas were spicy and flavorful. Highly recommended, though it’s worth noting that it’s a truck, so there is no indoors and no bathroom. Plenty of gas stations and such nearby, but you will probably be eating spicy, saucy sandwiches in 100+ degree heat. Still worth it.
