Born at the 1982 World's Fair in Knoxville, Tennessee, the Petro, a layered delight of Fritos corn chips, special recipe chili or vegetarian chili, shredded cheese, diced tomatoes, real sour cream, green onions, black olives and jalapeños quickly became a fan-favorite! The best part? The Petro and many of our menu items are 100% gluten-free. Other quick bites include vegetarian and vegan options, giant baked potatoes, black angus all-beef hot dogs, nachos and wedge salads, all made to order to your specifications. The refreshing Hint-of-Orange Iced Tea (infused with orange essential oils and brewed with dried orange rind), finishes off this not your average fast-food experience!
