If you want to see a show while you're in town, try and grab some tickets at Teatro alla Scala in Milan Centre. If you enjoy the show and want to see another, Teatro Dal Verme, Teatro Manzoni, and Teatro Filodrammatici are all a short walk away.
You can study the exhibits at Gallerie d'italia piazza della Scala, a museum with a storied past, during your trip to Milan. Add the area's stunning cathedral or shops to your travel plans.
