Spheres (hardturmstrasse, near by Eich Wyss Platz) is better known under its former name , Paris-Zurich . And the old name is still written on the outside wall.
This café is totally unusual. It is more a Share Space between a café and a library, where you can take a table (and drink a coffee) in the middle of books. You will appreciate the winter outdoor terrace, the quit mezzanine and probably this very special atmosphere, where everyone is focuse on his Own reading.
