After checking out several places selling produce in Philadelphia, I think the best ones would be:
- King Market at 10th street & Cherry street (Chinatown): for Asian fruits and vegetables that you will not find in American groceries.
- Iovine Brothers Produce in Reading Terminal Market (between 11th St. & 12th St., enter from the Filbert street gate): for many types of fruits & vegetables; produce here seems more fresh than at the King Market, and American fruits & vegetables here seems a bit cheaper.
Both places specialize in produce (so no meat, no dairy products), cheap and fresh.
Happy healthy eating 🙂
