National Cheeseburger Day, a made-up holiday celebrating this most American of foods, is here—and whether you like it topped with lettuce and tomatoes, Heinz 57, and French fries like Jimmy Buffett, or just plain, you’ve got plenty of options for a free or discounted lunch or dinner today.

National Cheeseburger Day occurs every year on September 18th, and while it has the same significance as National French Fry Day (July 13th) or National Chocolate Chip Cookie Day (August 4th), it’s still a great excuse to devour some comfort food.
