Klara's kitchen

All food served is vegan or vegetarian; the premises contain no meat or fish. The kitchen is built exclusively for vegetarian cooking. HappyCow marks both locations as 'Vegan', and Wanderlog identifies the restaurant as vegetarian. Staff understand plant-based diets well.

HappyCow categorises both branches as 'Vegan', and most dishes are plant-based. Multiple reviews state 'Everything is vegan' or that the venue 'has gone fully vegan'. Cow's milk is kept on the premises and offered as the default option for coffee, and the take-away listing confirms milk is available on request. This means the kitchen is not 100% dedicated vegan, and cross-contamination risk exists for strict ethical vegans. Staff are described as knowledgeable about vegan options.

Listings state that the venue does not use refined sugar, or 'no white sugar'. This is a stated policy, not a structural dedicated kitchen or marked menu. For individuals with sugar intolerance, this is a positive practice, but cross-contamination from naturally occurring sugars or alternative sweeteners is not addressed.

Wanderlog describes the cuisine at Klara's kitchen as having a gluten-free composition and includes the restaurant in its list of best gluten-free restaurants in Zurich. Multiple Google reviews mention gluten-free options. However, there is no evidence of a dedicated gluten-free kitchen, formal certification, or a marked menu with per-dish GF symbols. Staff are noted as friendly and accommodating to dietary restrictions, but cross-contamination risk cannot be ruled out.
