Join Us On A Trip Back In Time


When you’re looking for delicious food, generous portions and reasonable prices, Johnny J’s Diner has got you covered! We have two locations in Casper, and each looks like an authentic ‘50s diner, complete with a soda fountain counter and retro decor.

Check your worries at the door and step back to a time when life was simpler and the food was hearty and made from scratch — just like mom used to make! Our menu is simple and diverse, with everything from hamburgers and fries to hand-breaded chicken fried steak and real mashed potatoes to broasted chicken.

If you get up early enough, we do a bang up job on breakfast, too. It’s all made from scratch, and it’s all guaranteed to hit the spot. And hey — if you clean your plate, you can enjoy dessert guilt-free!

We can’t wait to serve you!
