I'm going with my wife to Europe from 27/March until 15/April and we are looking for some good place where we will can make the true/traditional Swiss Chocolat. 

Some course or workshop for a short period, there's something like that in some city of Switzerland?

I'm looking for local courses, more like "tipical/traditional" and not a tourist course like "Lindt factory" offers. 

Example of answers that I'm expecting and why I did not just googled it:

 - I know an small factory on a small city where you can learn how to do a incredible swiss traditional chocolat.
 - I know a good cheff who made some courses here in my city.
 - Zurich are not a good city for this, try to look at 'another city'
