Muslim in Switzerland - food and prayer timings?

Where in Switzerland will you be visiting. If going to small, rural villages chances are there won't be either, but if visiting some of the larger big cities than we'll be able to better advice.

I am staying in Geneva downtown near the train station. Is there any mosque where one can go to offer prayers?

I dont believe the country allows traditional mosques as voted against in a national referendum. Best suggestion is to find a quite park area and practice quietly or do so in your hotel room without the eyes of onlookers.
