Got their cheeseburger with everything on it. Tasted great. Great job on the seasoning.

I almost didn't go in because it looked like a hole in the wall on the outside. But I walked in and found that it is one of the cleanest restaurants I've been in for its size. They did not have gluten-free buns, but the cook made a fantastic lettuce wrapped burger. I'm really glad I went in. The food and service are all great!

Absolute amazing burger. I had just ordered myself and my son a cheeseburger with a malt and a side of chili cheese fries. Everything was absolutely delicious. Burger was huge and loaded with fresh toppings.
Cute little diner style place but it is a bit old so you may not fit in the booths. Also 2 burgers, fries, and a malt was nearly $40 which is rather steep.
However the food was delicious and the employees were super nice.
Yes, they take tap to pay here.

Always drove past this place, wondering about it… Today I got the chance to try their food. Now I’m wondering why I didn’t sooner. Small place, great burgers and BLT. The onion rings cooked perfectly. Their peach shake was amazing. I will definitely be back.

When I walked in I was immediately impressed with the cleanliness and aroma. When I tell you the burger was delicious that just does not do it justice. The juiciest most flavorful burger I've had in years. Dating back to the days of grandfather's backyard BBQ. The bun was toasted perfectly which added to the overall experience. An 11 out of 10. Will be going back soon. My compliments to the chef.
