These tours are top-rated and sell out quickly. It’s typically only possible to visit at night during the warmer months. Note that the Roman Forum is closed at night.
Rooftop bars and restaurants like Ristorante Aroma at Palazzo Manfredi, Mater Terrae at Hotel Raphael, and Hotel Forum Restaurant are all great options.
Roman gelaterias (gelato shops) are still open at night–some stores don’t even close until 2 in the morning! Don't miss Frigidarium, Come il Latte, or Old Bridge.
