Café Hummel is one of Viennas famous old cafés. They offer an authentic Viennese experience, while also providing excellent service (something not often found in old Viennese cafés). There aren’t many gf options (and I believe none of gf food options are vegan, just fyi) but their menu is very concise, the allergens are listed extremely diligently and the staff is happy to help. They have gluten-free bread, their egg-dishes are excellent and they have a wide selection of coffee and drinks. They do offer gluten-free schnitzel but it is not made in a dedicated fryer, so it’s not an option for celiacs. This is an excellent place for breakfast or coffee, for lunch I recommend Zum Wohl (Austrian Fusion) Pizzeria Scarabaccio (Italian) or Guru (Indian), which are all in walking distance
