Gelato is a must—and Michael’s favorite is at Frigidarium, a short walk from the Piazza Navona. If you prefer pastries, nearby Pasticceria La Deliziosa is a hidden gem where you can try one of Rome’s most iconic treats, the maritozzo. Afterwards, search the racks at Omero E Cecilia, Michael’s go-to vintage shop, for a unique souvenir.
