Unfortunately not recommended. I hate to give a bad review for a vegan restaurant, but the food is really bad and drags down the reputation of vegan food.
I ordered the miso ramen which, according to the menu, contains grilled vegetables and bamboo shoots. I received a miso broth with 3 pieces each of apple (?) and beetroot with a handful of spinach leaves. The gluten free ramen was overcooked. The soup was hard to eat, every pack of ready-made ramen tastes better.
I pointed out to the waitress that the ramen was very disappointing. The three of us then consulted with the person in charge of the restaurant at the counter, gave me a few looks and that was the end of the matter. There was NO response. The same behavior can be seen here in the reviews where there are no reactions to reviews from the owners.
This was my second and certainly last visit. There is simply too good a selection of vegan food in the city of Zurich to do something like that again.
