The two of us went here for lunch on a Saturday and got a table by the window without having to wait. I chose the restaurant because of the beautiful view and even though it was cloudy, we had a great view of the countryside. The food was ordered quickly, there was pizza vegetariana for the gentleman and rabbit with polenta for the lady. The food came unusually quickly and was delicious!
A big plus point is that the dishes are labeled as to whether they contain gluten, etc.
In terms of price, you've already noticed that you're paying for the good view here, table service for €4 per person is quite a bit.
Nevertheless, we really liked it and it was just right for a day visit to Bergamo!
