A historic cafe. Now It is a touristic place but not as a bad touristic place. You can see several great paintings on the walls. Deserts, coffees, and drinks are fine but too expensive.
Brioch was the most hideous cornetto I've ever eat in Italy. Very mushy probably they heated at microwave and I wouldnt call that sticky brown thing as chocolate so it wasn't nutella for sure!
Prepare to pay more if you are going to sit in, and don't stand in line, waiters will serve you, unless you take out. I had a cappuccino and it was average (for 8 € !). The Panna Cotta was just that.
