A stroll around the Quadrilatero d'Oro, the world's most famous shopping district, is a must. This quaintly cobbled quadrangle of streets – bounded by Via Monte Napoleone, Via Sant'Andrea, Via della Spiga and Via Alessandro Manzoni – has always been synonymous with elegance and money (Via Monte Napoleone was where Napoleon's government managed loans). Even if you don't have the slightest urge to sling a swag of glossy carriers, the window displays and people-watching are priceless.
