Bar Tre Scalini is located in the famous Piazza Navona, a charming pedestrian square in the center of Rome. The bar is right next to the Bernini Fountain so it is the perfect place to relax with a drink after visiting the fountain. But, the restaurant was not perfect. Everything is frozen or prepared ahead of time and microwaved. Do you really want to eat frozen pizza in Rome?. The staff was also not very nice and seemed more interested in attending tourists than anything else. However, the gelato is very good. You get two generous scoops of gelato for about 3 euros and it's very tasty and refreshing.
