I (@lamouthe) lived in Switzerland for almost 7 years, and after reading your post, I just realized... I never went to Zurich!!! Shame on me!!! :P
Maybe I didn't visit Zurich, but I saw quite a lot of other very beautiful places : Lausanne, Fribourg, Lucerne, Bern, Interlaken, Sion, Locarno, Lugano...
