The restaurant is centrally located and nicely designed, with a modern decor still respecting the traditional architecture of the building. It is very spacious, ideal for big groups. The service was very fast and attentive. Best of all was the food, though: I ordered a "Kümmelbraten" (a kind of pork stew) and it was outstanding, among the best typical German food I have had in the past ten years. The prices are pretty normal for a restaurant of its category.
Overall highly recommended.
