Try north Philadelphia. There's a ton around York dauphin.

There's Vilmas on Howard and dauphin. There's El principal on Howard and Lehigh. There's corner stores galore. There's another nice spot called Boricua close to Girard and 3rd.(second one down aramingo)

El coque is super deep north in the badlandz but good food.

I'd say definitely anything west of berks station. There's also a spot on handcock and diamond. I forget the name but it's awesome Spanish food. A bit pricier.
