Sept. 18 is National Cheeseburger Day, and the food holiday means plenty of opportunities to save on burgers at chain restaurants around the country.
What classifies as a cheeseburger can take on many forms these days, from turkey burgers topped with Swiss to flavorful bison burgers served at a gastropub, but there’s something to be said for a traditional, slightly greasy beef burger topped with melted American cheese.
And plenty of restaurants are celebrating the classic cheeseburger on National Cheeseburger Day, including sit-down spots like Buffalo Wild Wings and fast food chains like Burger King. Read on for eight restaurants offering BOGO, free, and discounted burgers on Sept. 18.
