Can you ever have too many tacos? Surely not. Shanghai has gotten one more spot with an outpost of Tacos in the unlikely back alley food street of Pudong’s FOR mall. With locations in Xiamen, Shenzhen and as far afield as Thailand, the taqueria slings fajitas, quesadillas, creamy queso fundido topped with chorizo and other Mexican fares. There are, of course, tacos with filling choices like fish, chicken, shrimp and pineapple-flecked al pastor. Wash it all down with smoky mescal margaritas.
