Restaurants in Switzerland

The density of restaurants in Switzerland is high. The variety is very broad, as many different cultures in Switzerland run restaurants with their national specialities. In Zürich. you can easely eat out every night and not have to pick the same nationality for a cupple of weeks.
Eating aout in restaurants doesn't require any special knowledge, exept the "Stammtisch" and the "Tipping" rules.
The Stammtisch is the table reserved for the regulars. It's a no no to take your seat there.
Tipping is not compulsary in Switzerland. If you liked the Service, it's a nice gesture to do so and very much appreciated. Usually 5 - 10%.
