This restaurant is right by the shore of Lake Albano. We visited it for the third time in May 2014 and still found it one of the best experiences in the area. Firstly the location is perfect. You can sit outside or in and see the lake and surrounding hills. The staff are friendly and helpful and the food is authentic regional food of a high quality. You know that you are in a good restaurant when it is full of Italians!
If you feel energetic you can walk round the lake in 2 hours. There is a path that continues after the road finishes and you will see all sorts of wildlife including terrapins in the lake!
Certainly Da Agnes restaurant is a perfect lunch stop.
