The price has gone up a bit, but this place makes a burger that has me smiling whenever I bite into it.

Sooooo, my husband took me to this place because I’ve never been and wanted a really good burger. It had 4.5 rating so I took a chance. I’m glad I did. When we walked in we were greeted warmly. It’s a hole in the wall vibe but very clean. Our chef was Serena, and boy oh boy did she craft us an amazing tasting double cheeseburger. We even asked for a medium cook and she delivered. We also ordered the onion rings, French fries, and a pineapple shake. These are a MUST!

This place is a definite recommended!

Oreo milkshakes are so so good! The ladies that work here are so nice and welcoming. We come here as a family as often as we can. Now that my son is an adult he makes it here on his own and with friends. Great place, go and try them!! Won't disappoint.

Hi there,
My experience was on Monday July 28 at about noon. I ordered 2 Bacon Cheese Burgers 1 French Fry and a couple of Cokes.
On one of the Cheese Burgers the Letuce was soggy as a wet rag and over loaded with Mayo, pretty gross and the French Frys were like a limp, you know what I mean..
Talk about being a little pricey, it cost me $55.00 plus a $5.00 tip.
I could tell you one thing, this guy will not be going back anytime soon.
I hope this helps you out with your decision weather or not to go to this establishment.

This is a small mom and pop type place. Typical hamburgers and chicken sandwich type stuff. The restaurant was absolutely immaculate. I’ve never seen one this clean. The food was really good and the onion rings were the best I’ve ever eaten. Prices were about the same as your average fast food restaurant, but the food was a much higher quality. I had a hotdog, and my friend had a cheeseburger which he loved. If you’re in the area and hungry, I would definitely check this place out.

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.
