Try:

Miyuko
Beckenhofstrasse 7
8006 Zurich, Switzerland

It's a cute little cafe which is owned by a Swiss lady but is Japanese themed.
For chf 18, my friends and I had prosecco, 1 macaroon, piece of cake and coffee. They try and incorporate tea into the cakes which is really interesting and quite tasty.

They also have themed afternoon tea and brunch I think.
