Time Out says
Chuchi am Wasser is best enjoyed outside from its riverside terrace. Lunch menus change daily and there's always a vegetarian option. Indoors is cosy in winter.
The 'kitchen by the water', part of culture and youth centre Dynamo. It is best enjoyed outside. Daily changing lunch menus (including at least one vegetarian option and a vegan menu on Wednesdays) using local ingredients, light snacks and cakes are served on its terrace right next to the river. Watch Zurich's more daring youth take a dip right outside the café and float with the current down to the Badi at Letten. Indoor seating is rather dark and cramped, but it feels quite cosy in winter.
