Our server brought out the hot chocolate package so we could read the label. She researched that they do not have a dedicated fryer but the mashed potatoes with no gravy are safe. Great experience and great food.
The waiter was very knowledgeable on what I could have gluten free and taking precautions to avoid cross contamination. It was a very good meal.
One of their waiters can neither eat gluten not dairy and we were advised which items on the menu are gluten free -- luckily most of them, including all the sauces.
