You need to take a detour from the regular skitrack. You'll make left at some point and enter on a narrow road (groomed, so that you can keep skiing). Just follow the road into the forest and at some point you will see the Hut.
I don't know if it was the fact that we were very hungry or not, but here we had the BEST Bratkartoffel until now. The view is splendid, and after you are done, you can ski down the road for 10-15 minutes and you will get to the skilifts.
The menu is quite simple, you have about 3-4 choices.
Just to be clear, this is not a Michelin star restaurant. It's a quick bite place.
Great pitstop after a few hours of skiing!
