More cheesy deals are expected to be announced this week! Say cheese! There are lots of cheesy reasons for bargain hunters to smile on National Cheeseburger Day, September 18, 2025. While there are many stories regarding the birth of the cheeseburger, many believe it all started right here in Denver. Back in 1935, a trademark for the name “cheeseburger” was awarded to Louis Ballast of the Humpty Dumpty Drive-In in Denver.

The only true story is that everyone loves a juicy cheeseburger. Even better, when it’s with fries and a shake!
And, because of the endless possibilities of the bun, cheese, condiments and toppings, everyone can create and enjoy their own “perfect cheeseburger.”
The deals are only valid at participating locations and cannot be combined with any other discount or promotion. Limit one offer per person, while supplies last.
For most, there are no protein substitutions allowed — only beef burgers. Plus, none of the offers are available for third-party delivery.
