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!

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.

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...
