Pat's King of Steaks and the cheesesteak internet debate

Pat's King of Steaks, at the location owned by the Olivieri family since 1930, claims its founder created the cheesesteak by putting sliced beef and onions on an Italian roll; that origin is a local claim and the exact origin is debated. The long-running rivalry between Pat's and nearby Geno's has fueled numerous viral taste-test videos, social-media debates, and food-listicles comparing Philadelphia cheesesteaks. Both shops are frequently featured in online content about Philadelphia's food culture.
