They almost always have one gluten-free cake available (Schokotarte) and maybe one other small cake with kiwi, but that one is not often available (gf is marked on the little cards). You can also order a unique cake (for birthdays e.g.) which is then hand made and not cross conterminated I believe. They also have some warm food, but always ask the server for gluten because it’s not marked in the menu.
— No gluten-free information on the menu
— Not Much
Always one gluten-free cake available, owner has knowledge about cross-contamination.
