The votes are in. After a close battle, 80/20 @Kaelin's Restaurant has been named the best cheeseburger in Louisville by our readers.

Kaelin's is locally lauded as the inventor of the cheeseburger + after looking into this claim we learned that most historians credit Lionel Sternberger of Pasadena, California as the inventor of the American classic in 1924. But, we found this awesome story by The Courier-Journal from 2015 exploring the origins of this tale with 85-year-old Irma Kaelin Raque — one of Carl Kaelin's children.

Congrats, Kaelin's. 👏
