We went there a Saturday evening, wihtout reservation. We managed to get a table in the main room, after refusing a table near the toilets, but the "manager" seemed determined to shorten our stay. The food was average: pizza was ok but the pasta and deserts not so great.
The bad part was the service: they practically thrown the plates on the table, they forgot to bring us a bottle of water (they never realized as we gave it up) and they didn't even bother to answer when we thanked for the meal and left.
They had a lot of people eating there so probably they didn't care much about some tourists they will never see again.
