Philadelphia has a well-earned reputation as a great sandwich city. How many other cities, after all, can lay claim, as Philadelphia does, to the invention of three iconic sandwiches? According to Visit Philadelphia, the city's sandwich trinity is comprised of the hoagie, the roast pork sandwich, and the Philly cheesesteak, with their respective creations most likely occurring in that order.

The roast pork sandwich, for instance, had its genesis in Italy, but the Philadelphia version was created by Domenico Bucci in 1930 in a South Philly eatery that's now named for his son: John's Roast Pork.
