Overall, it was very good, and the service was very friendly. However, it gets -1 star for the fact that they advertise a gluten-free bun. Unfortunately, there is a disease in Germany that prohibits eating any gluten, meaning grains, flour, etc. Even crumbs of it have serious consequences. It was really difficult for one person to find something they could eat. I would be happy if it were labeled "gluten-reduced," so everyone would be aware that the kitchen unfortunately doesn't/can't adhere strictly to this.
I would also like to see the allergen menu updated; unfortunately, there were some dishes on it that are no longer available.
