The views of Rome from this sixth-floor hotel restaurant are jaw-dropping, with a gorgeous panorama of the old city glowing pink and peach as the sun goes down. The food is equally special, with head chef Francesco Apreda’s reinterpretation of regional Italian cuisine borrowing heavily from Indian and Japanese culinary schools. Menus are seasonal, but might include duck breast tandoori-style, sake-glazed black cod with purple baby vegetables, or even lavender-flavored casserole of quail and sea scallops. Reservations are essential, and men need a jacket at dinner.
