What could be more romantic than a candlelit dinner on a 1940’s tram with Rome’s Colosseum and live jazz music as your backdrop? On the recently launched Tramjazz (tramjazz.com; tickets for two $160) tour, you’ll drive by historic sites lit up at night while enjoying plates of eggplant lasagna and ricotta tart. The best part? Your traveling companions include a troupe of local musicians.
