if you want the real authentic stuff you need to come right to the source. the philly italian market. Sarcone's deli, Di Bruno Bros. cheese, Isgro pastries, everything is right here. you can easily spend 1/2 day just walking around buying stuff, ducking into the different shops, eating lunch, and of course buying fresh bread, pasta, cheese and wine to take home for dinner that night.
Pros: DiBruno Bros, Sarcones, Isgro
