Good shopping streets include Via Dante between the Duomo and Castle, Corso Vittorio Emanuele II near the Della Scala square and via Monte Napoleone near the Duomo. For exclusive fashion, head to the surrounding area via Della Spiga known as the Quadrilatero d'Oro or Golden Quadrangle, which includes Via Montenapoleone, Via Andrea, Via Gesù, Via Borgospesso and Corso Venezia. Corso Buenos Aires has less expensive boutiques and chains, many of which are even open on Sundays. Of course, if you don't want to spend a lot of money, window shopping is also fun.
