Fresh Tortillas in the South Bay?
If you are looking for corn tortillas, Tropicana Market in SJ makes tortillas "in-house", they are machine made, not hand made. If one arrives early in the morning, one may see people buying tortillas by the hand truck load, i.e., 6-8 cases at a time. Tropicana is located at King and Story Roads.
Chavez Market advertises they make their tortillas "in house", but I am not sure what location.
