We were drawn to this restaurant due to the beautiful location next to the castle with a lake view from a terraced balcony. The hotel looked good too. We were first met by a lady who seemed to be working on the hotel desk, and was very pleasant. She handed over to a male waiter, who was the worst waiter I have ever experienced. He was incredibly rude, unaccommodating, and made us feel very uncomfortable. We considered leaving after ordering drinks, but stayed on giving him the benefit of the doubt that he was having a bad day. Things went from bad to worse, however. My partner wanted to try the local trout, which came with a side of boiled potatoes. When asked if she could swap potatoes for pasta (arguably making the dish more Italian...?) she was told "I don't know why you would want to commit such a sacrilege"!! We were both astounded but he continued... "I don't know why you would do this?" he went on... When the food was served, it was simply ok. We had a side salad between us, which we didn't finish. As you can imagine, comments and facial expressions were made when he cleared things away. The restaurant was completely empty at the time, and it's no wonder that the others are full when you compare the service. Avoid the mistake we made after being seduced in with the location and go elsewhere.
