I had pizza. Very nice, tasty. I was informed it is fully gluten-free but they bake it in the same oven. I didn't have any symptoms (and I always have symptoms if there are traces of gluten in a meal)so in my case it was fully safe. In the menu there is information about glutenfree option (additional 2Euro)
