Say cheese! There are lots of cheesy reasons for bargain hunters to smile on National Cheeseburger Day, September 18, 2023. 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.
