The flavors at this small gelato shop are creative and refreshing, like ginger and apple, mixed citrus and fresh chili pepper, and one option made with beer. There are also refrigerator cases for individual portions of semifreddo desserts like tiramisu and zabaglione. Take your cone across the street and peer over the railing to see the spot where Julius Caesar was assassinated—today, it’s filled with lots of lazy, well-cared-for kittens.
