If you ever spend some time in Thusis and you love the homebred local cuisine, you definitly have to book for a dinner at the Restaurant Gemsli in Flerden. Flerden is a small village 500 meter above Thusis.
Search for Restaurant Gemsli Flerden in Google Earth or go to the local site (in German only).
The first time you try to enter the Gemsli, don't be scared off by the impression of the Restaurants facade from outside. Inside you will find a homebred but cosy farmersroom with a large and warm oven. You will feel comfortable.
