I went there with my brother (also a celiac) once and we had currywurst and Ragout fin. Both was proclaimed gluten free and didn’t cause us any stomach pain afterwards. Our waitress even went to the kitchen to ask, if the Ragout fin is gluten free. It was, except for the bread but they just didn’t added it. The menu marks, which dishes contain gluten and which ones don’t but it’s not always right. For example, they have bruschetta, which is definitely not gluten free but didn’t mark it as a dish, that contains gluten. So it’s better to ask beforehand.
