The first branch of Giolitti's ice cream shop opened in 1900. It is rumored that some of the secret recipes of the ice cream shop are kept by the owner in a safe. Regardless, it's an authentic and well-known place.
The ice cream parlor is so old and popular that it is said that even Pope John Paul II used to ask for Giolitti's chestnut ice cream. Even today quite a few celebrities and important people visit the ice cream parlor, including Michelle Obama, the wife of the president Obama, who requested ice cream from this very place.
If you want to taste one of the classic ice creams that have been served here since the 192'0s, ask for this combination: chocolate ice cream, crispy zucchini pudding with whipped cream, hazelnuts and waffle rolls. All customers recommend the luxurious addition of whipped cream.
The Romans attribute so much respect to this dish, that they offer "authorized" ice cream shops, places which only deal with the preparation and production of ice cream. Note that the price here is determined by the amount of ice cream and not by the number of balls ordered.
