The Italian-American restaurateur Pat Olivieri is the self-proclaimed "inventor of cheesesteak." Co-founded in 1930 with his brother, Harry Olivieri, their historic eatery began as a simple hot dog stand. One night, the brothers decided to keep working and, tired of hot dogs, cooked a steak while they waited for more customers. A nearby cabby asked if he could have one of the steak sandwiches they were grilling, and the cheesesteak was born. Today, inside their sedate brick eatery with fluorescent lights, the standard order is simply a “Whiz Wit,” a cheesesteak with Cheez Whiz and grilled onions. Customers are told to be prepared and know how to order. For example, on a cheesesteak with onions, customers should specify which kind of cheese they’d like (Provolone, American or Cheese Whiz). At the next window, diners can pick up soda, fries and coffee. Cooks slide the piping hot sliced meat sandwich, wide open and unwrapped, across the counter to customers waiting outside, where they can add ketchup, mustard, relish and Joe's hot sauce
