Great customer service, we are extremely pleased with how kind and attentive the staff is. Special mention for Jonah, he was awesome, completely took care of us, management has a jewel in him for sure! God Bless!
My husband and I ordered two grilled cheese sandwiches and two cheese fries. When we got home, we discovered chunks of meat inside one of the grilled cheese sandwiches (see photo). We're both vegetarians, so this wasn’t just a mix-up. It was a serious breach of trust and food safety.
It appears someone in the kitchen may have started preparing a cheeseburger, realized the mistake, and made the poor judgment call to remove the meat and serve the sandwich...

If you're looking for something quick and tasty — this is the spot. The service was fast, the burgers were juicy, and the portions generous. A great option when you're short on time.
