We ate at polpetteria in October. The polpetteria are small balls of stuff which are its speciality. My wife had the fish of the day grilled which was large and not hugely expensive. The restaurant is very busy with lots of Sicilians and that's a good sign. We ate outside which was pleasant as it was still hot. its in the same street as Sale which was also recommended to us but we didn't have a long enough stay to try.
only downside was that only one waiter had good Engish and for some reason we ended up with our allocated waiter, the maitre d' and the trans;ator all gathered round which was a bit intimidating.
House wine was good as was the steak that I had. Good solid mid level restaurants, a bit different from the usual trattoria.
