The employees were super nice and the service was great. Really no issues there. However, the food was terrible. What should have been a super flavorful burger (PBJ) was very bland and the smashed patty was way over cooked (like crispy/burned, over cooked). The fries were overly greasy and flavorless, despite being covered in parm cheese and garlic. However, my daughter's grilled cheese and regular fries were super good! Kind of shocked that the regular fries had more flavor...

Definitely eat here! I had the shroom and Swiss burger with fries. It was amazing! Best burger I've had, the fries don't need any dipping sauce, although they offer some. The price is great and the service is excellent!

The hamburger was absolutely delicious cooked fresh with fresh meat the buns are like some type of potato bread super delicious. They had a variety of fries that were amazing. And it's in a place where they have a bunch of food trucks so you have a lot of food to choose from but this place is so delicious and they even have tables to go eat your food at. Perfect for the whole family.
