Miyuko is a small, but very lovely place in the centre of Zurich. You can get a vegan brunch or Afternoon Tea - including croissants, scones with cream, fruit, small sandwiches and pies, Birchermüsli, and (the best) cake and other dessert items. Everything tastes great, and the cakes are just stunning! They even have vegan "Bieberli" and meringue. The staff is very friendly and always open for special wishes (gluten-free etc.).
Cons: Closes at 6pm
