If you can do only one thing in Milan, be sure to see Leonardo da Vinci’s The Last Supper, housed in Santa Maria delle Grazie Church. Plan ahead — even calling a few weeks or months in advance is a good idea — as reservations are required to secure one of the 15-minute slots to see the recently restored masterpiece. Call for reservations (tel 39 02 8942 1146) between 9 a.m. and 6 p.m. on weekdays and 9 a.m. and 2 p.m. on Saturday. Visiting hours are 8 a.m. through 6:45 p.m. Tuesday through Sunday. Some online agencies also sell reservations, but there’s usually an additional service charge.
