I went here last October before camping at a campground a ways out of town, and let me tell you, this place has the best French fries I've ever had. Crispy, flaky inside, delightful french fries. People working seemed very nice too. A bit of a smaller place, probably best for 1-2 people, not a big crowd place, but absolutely delicious food. Milkshakes were outstanding as well, but the fries! That's what you should get here.

We travel a lot and have tried a lot of different burger places but the Corner Lunch definitely takes the cake! The smash burgers were great, seasoned well and had the perfect smash burger crisp. A great variety of options for toppings! Beer cheese and bacon fries were delicious, fries were awesome. Banana cream pie shake was perfect. Overall the best burger and fries we’ve had anywhere. Staff was very kind and welcoming as well!

Small joint, with cute diner atmosphere. The food was FANTASTIC. A large to go order came in before we placed our order, and the kitchen worked diligently to complete all orders before and after ours. The smash burger I had exceeded my expectations, the kids meals were good portions and my kids enjoyed them. My husband also really enjoyed his burger. We shared a large poutine that was not light on anything- heavy on the fries, gravy, cheese, chives, and flavor. Service was kind and accommodating, cheerful and gracious. Worth the 45 minute drive for us. We will definitely be back.

It’s a former gas station that has many selections of hamburgers and french fries chili dogs. I got the double cheeseburger and poutine fries. Can’t wait to get back in the area again to get the poutine fries once again.
