Seriously... You will likely feel sick afterwards, but it is soo worth if if cheese is your thing. Gruyère or Emmental cheeses are the best to sample as far as Fondue goes. They also do amazing chocolate fondue, with fresh fruits dipped in the melted Swiss chocolate. So good!
Switzerland is generally a good place for both cheese and chocolate, but most people do not realise how good the quality of the wine is either - I strongly recommend some tastings if you can get yourself to some vineyards, depending on the time of your visit. almost 8 years ago
