Step into Milan's 'living room,' the Galleria Vittorio Emanuele II, right next to the Duomo. You don't come here just to shop; you come to feel the city's pulse. Look up at the incredible glass and iron dome, find the bull mosaic on the floor for good luck, and just wander. It's a stunning piece of history where you can browse high-end boutiques or simply enjoy a coffee while watching the stylish world go by.
