About Philly Steak Factory...

The Philly cheesesteak sandwich was developed in the early 20th century "by combining frizzled beef, onions, and cheese in a small loaf of bread," according to a 1987 exhibition catalog published by the Library Company of Philadelphia and the Historical Society of Pennsylvania.

Philadelphians Pat and Harry Olivieri are often credited with inventing the sandwich by serving chopped-up steak on hoagie rolls in the early 1930s. They began selling his variation of steak sandwiches at their hot dog stand near south Philadelphia's Italian Market.

Today the tradition lives on at Philly Steak Factory. Come taste for yourself what made the philly cheesesteak such a success.
