The restaurant is one of a series which was started with the prince's restaurants at his castle at Kaltenberg. The other's are named "König von Bayern". It's nice, typical Bavarian food, nothing spectacular but well presented, not overly expensive and served with the very good beer from the prince's brewery Kaltenberg. As Kaltenberg Castle is only about 10 kms from here, we like to go there in summer because it's a fun place to be. I especially like his dark brown Ale "König Ludwig Dunkel". In addition the prince organizes a historical (medieval) festival with tournament and markets there every summer - very good entertainment.
