Editing my review after having gotten cake there twice.
My first time I was able to have a delicious slice of lemon meringue pie! At the time they didn’t have any places to sit and eat, but I was able to get it to go and it survived the train ride home.
My second time I got an amazing slice of red currant cake. They now have seating open, so you can also sit and have the proper Kaffee und Kuchen experience. While all their cakes and breads are gf, be sure to ask them about their chocolates and packaged goods, as not all varieties are gf. They get some of their chocolates from other producers, but their house-made chocolates are gf, so from a preparation/kitchen standpoint it’s still very safe for celiacs
— Yes, the establishment is dedicated gluten-free
— Excellent
