When I questioned the waitress about gluten free items she immediately (courteously) opened their gluten sensitive menu on the table electronic screen. The waitress seemed well aware of gluten concerns. There were plenty of menu items offered there.
I had one of their burgers on a gluten free bun with baked potato. I questioned the table runner if the burger bun was gluten free and he replied yes immediately.
Food was very good and I was very pleased with the food I was served.
