I don't give 5 stars for a simple reason: we asked for tagliatelle with mushrooms (really excellent and plentiful) and cannelloni with ricotta and spinach with béchamel sauce. It's a shame that the latter had béchamel sauce with mushrooms, which wasn't written on the menu and since it wasn't popular, they changed it to tagliatelle with meat sauce but canned meat sauce (the smell is unmistakable). They would have made a better impression by offering us something of their own production or telling us that they had no other first courses or at least immediately warning us that the writing on the menu was wrong and/or incomplete.
After pointing out the "Star ragù" they at least offered us the bitters.
