About Zurich

Hi Ints community!

I am writing from Geneva where I live, because I have a friend 25 years old visiting Zurich for a week in January . I would like to ask you specially those living in Zurich tips on places to go, visit and shop:
- trendy resto, discos.
- fashion shops
- upcoming neighborhoods
- where to find latest brands/designs?
- typical swiss places to visit
- shows or festival in january?

Many thanks indeed!

Carolina
