History
Philly Cheesesteak
Pat Olivieri invented the cheesesteak in the 1930s. Olivieri was a hot dog vendor in south Philadelphia who, as the story goes, decided to grill some beef from the butcher and put it on an Italian roll. A cab driver caught a whiff and asked for a steak sandwich.
Word spread rapidly through the cabbie rumor mill, and drivers from all over the city soon visited Olivieri for steak sandwiches. Olivieri eventually opened up Pat's King of Steaks on 9th Street and Passyunk Avenue. Cheese was added to the mix in the '40s
