I visited the harbor area of Hamburg for work and asked this restaurant if they were able to prepare some dishes gluten free for Celiac, and they could adapt some of the main meat or fish dishes, as well as offer gluten free spaghetti noodles. They even made a special veggie sauce and dish for my gluten free pasta since I am also vegetarian.
— Somewhat
— No gluten-free information on the menu
