Nice restaurant in the heart of Lucerne. They offer gluten-free pinsa. It was very tasty and the staff were friendly and attentive. The pinsa was delicious - the gluten-free version is baked in a separate oven. We felt reasonably safe overall. However, all pinsas are on wooden boards/plates which have more or less deep cutting grooves.
We pointed out that it would definitely make sense to serve the gluten-free pinsas on plates or dedicated boards to avoid cross-contamination. They were very open and appreciated the suggestion. I assume they’ll handle it even more safely in the future - otherwise it’s best to just ask for a plate instead of a wooden board when ordering. Our daughter is a symptomatic celiac, but she had no issues and really loved the food.
