Edit: we had a problem with a visit awhile back that I brought to management's attention and I am updating my review today based on that.
They were very responsive and took responsibility for the situation and provided a nice incentive for us to return and try them again. We went today and had a great experience. We were seated immediately and greeted by our server shortly thereafter. They have a great gluten free menu that includes tasty crispy baked fries and a gluten-free bun for any of their hamburger offerings. We enjoyed a nice meal. I love the way they serve their soft drinks in frosty mugs. I'm happy to give them five stars and look forward to returning again in the future. Yes, it is a little expensive. But all things considered it's a place I will be happy to visit from time to time. Also, the floats are enormous! We will be back to try those out.
