Neat little lunch spot to check out. They do have the kind of onion rings I like (thin and crispy) and the burgers are the smash style type. Worth a visit to try.

Their "Classic" burger is the quintessential American burger. Perfect size, perfectly dressed and so tasty. It's that simple burger that people have forgotten how to make! The fries also perfection. Flat fries a little thicker than a potato chip so that they are crispy and soft at the same time...brilliant! I have also ordered a meatball po boy to go. My order was taken promptly. The whole sandwich was toasted, meatballs were super delicious and the wait was short. I also had the house made potato chips which were great. Friendly service in a very clean and friendly atmosphere. The menu is simple, which to me translates to fresh food. I liked it a lot and will be back.

Owned by the youngest Swindle, Brandon, go head boy. Excellent food and service. Had the sensation salad (excellent), the sweet & spicy salad (lettuce could have been fresher), tex mex eggrolls (like most any other resturant, chilis calls them southwest eggrolls), fried chicken sandwich (excellent), fountain drinks with coke products. I had a half and half sweet unsweetened so not sure which one tasted like the fake Nestle premade which I'm not a fan.

My wife and I were flea marketing on a Saturday and decided to do lunch. I did a Google search and found this nearby and we decided to give it a try. I must say we were impressed. The food was PHENOMENAL, the service excellent. The help and other patrons we're super friendly, to the point one of the other patrons started singing to my wife. We all had a delightful lunch and we will definitely go back on our next trip to the area.

I actually called this one in and bought it back to my place of work so i didn't get to experience dine in. I did have to wait an hour for my wrap but i think its just an issue with the website. Definitely call instead of the website! I got the Cranberry Sensation wrap with chicken, and the fried ravioli BOTH were awesome! never tasted a wrap like that! Very unique, very "one of a kind". The fried ravioli was also great ! 10/10 on the taste. Also, the hostess was very nice to us and made up for the wait. Will definitely go back to try new things.

Visiting the area and found this local joint with 4.9 stars, so we were sold. Took a bit to get our food but it was worth the wait. Our poboys were delicious and you can’t go wrong with either fries or onion rings. Both were crispy, thin cut and yummy! Hostess was very friendly and was also giving away gifts to customers.

Excellent service, friendly staff, delicious food! My kids even cleared their plates! The fire shrimp burrito was huge and had just the right kick to it. The kids burger was larger than expected and my daughter ate every bite! We all really liked the homemade potato chips and chili cheese fries. Best fish tacos I've had too!
