Visiting Zurich

Hi all,

I'll be spending a week in Zurich from 26 Mar

Just wondering are there places I must go to in order to get my share of the "Switzerland" experience? Is it worth it to travel to other parts of Switzerland if I only hav 6 days there?

Since I hav never ever set foot on this beautiful country, any help would be appreciated...
Thx a lot

Cheers
April
