Petro's Chili & Chips

Joe and Carol Schoentrup of Spokane, Washington, along with Joe's sister Ann and her husband Mark Lawrence of Kennewick, Washington operated a food concession at the fair that served a combination of chili and corn chips that they dubbed the "Petro", a name derived from "petroleum" to honor the energy theme of the 1982 World's Fair."[1][3] For the World's Fair, the Schoentrups said they "gourmetized" this combination by adding cheddar and Monterey jack cheese, tomatoes, green onions, sour cream, and hot sauce.[4] Petro's primary product consists of corn chips topped with either meat-based or vegetarian chili, cheese, green onions, tomatoes, and sour cream, all served in a cup.[6] The menu also includes Premium Petro Toppings like BBQ pulled pork, grilled chicken, queso and zesty guacamole, as well as all-beef hot dogs, salads, giant baked potatoes, and fresh-baked cookies.Hint-of-Orange Iced tea served with an orange slice is Petro's signature beverage.
