Open atmosphere dining, sort of loud inside. Lots of kids, kid friendly environment. There is a bar section for adults which look comforting. The meatballs were hand rolled, yay. The cheese bread went great with the meatballs! Both are appetizers, but was more than filling enough to be a meal. The sweet tea is chilled and tasted so good I took 3 glasses!

We were greeted and seated promptly. The service was fantastic, our waitress was amazing! As someone with food allergies, our waitress explained how the gluten-free foods were cooked and even shared her own experiences having food allergies. That in itself made this experience that much more worth it.
As an appetizer we had the naked wings, omg so crispy, flavorful and delicious. We also had the gluten-free mighty meat pizza, one of the best pizzas I've had in...

Had my favorite shitake mushroom pizza delivered. It's a bit pricey with delivery but great for a treat. The pizza is amazing and it got to me quickly. I highly recommend you try Mellow Mushroom in person or order online & pick up or have delivered for a few.
