Another restaurant, which is always a "must" during our visit in Germany is the Ruehrborn in Diedenbergen.
They have a wonderful atmosphere and deco there and you can also see the traditional Fachwerk-architecture there.
One of the "highlights" in this restaurant is the Kloster Weltenburg Beer, they serve. Kloster Weltenburg is a cloister in Bavaria and it has a traditional brewery... the oldest cloister brewery in the world (since 1056) and the beer is delicious.
The food delicious, too... here is the menue, I always order there...
