Jim & Arlene Moser opened Jim's Burger Haven in Thornton, Colorado, more than 50 years ago. Diners flocked to Jim's for its signature six-inch smash burger — dubbed as a "square meal on a round bun."

Jim’s Burger Haven has served Colorado's original six-inch smash burger since 1961, a place for friends and family to gather over a classic meal of burgers, fries, shakes and more.

BURGERS The Original 6-Inch. Local, Colorado Natural Beef & Aspen Baking Company bun with yellow mustard, shaved lettuce, tomato, onion & pickle. Served plain or with American cheese - Single, Double or Triple Beef Patties. The 4-Inch.

Whether you just don’t want to face the crowds and relax in the comfort of your own home or if you’re too busy with work for a lunch away from your desk, don’t worry. You can still take our famous burgers, malts & shakes and enjoy wherever …

We are constantly adapting how we can best serve you by monitoring and following the government safety recommendations surrounding COVID19. Right now, you can dine with us in three ways: pick-up, delivery (through DoorDash), or inside our dining rooms with limited capacity.
