Tau Vegan Restaurant
100% dedicated vegan kitchen with no animal products on premises. HappyCow categorises Tau as a 'Vegan' venue (not merely veg-options), established September 2020. Reviewer Puschelbubu explicitly notes '100% vegan' among pros; DanielPauxberger states 'Alles vegan und extrem gut.' The venue's own online menu lists every dish as vegan (or plant-based vegetarisch in context of a vegan kitchen), with mock proteins (Sojafleisch, vegane Ente, vegane Garnelen) confirmed as entirely plant-based across the full menu.

Not appropriate, Documented unsafe, multiple negative reports, or refuses to accommodate. Surfaced to warn rather than recommend.
Soy meat ('Sojafleisch') is the dominant protein used throughout the entire menu — it appears as a primary ingredient in noodle soups, fried rice, fried noodles, rice-noodle dishes, starters, and mains. Avocado Rolle explicitly lists 'Sojafleisch' and Sommer Rolle lists both 'Sojafleisch' and 'Sojabohnen.' Edamame is also served as a starter. No soy-free accommodation is evidenced anywhere on the menu or in any review. This kitchen is structurally unsuitable for anyone managing a soy allergy.
