New to the board, new to the city! Recently arrived in Philly from a long stint in the Bay Area, where I often cruised the local Chowhound board, but never participated. Being new and loving to explore (especially when food is involved), I was hoping someone(s) could suggest 4-6 great, low-to-moderately priced places to do a food crawl in and around South Philly. I say South Philly because that's where I live, but I'm open to suggestions in other locales of Philly, too. The only criteria is that the destinations are within walking/biking distance of each other, and that they are delicious!
