Alfies Antique Market has drawn collectors, celebrities, and interior designers alike to carouse through the array of antiques and collectibles for more than 30 years. Just north of Marble Arch, the elegantly bohemian boutiques always hide treasures waiting to be dug up. The merchants here are refreshingly friendly, and definitely bring in the know-how, be it for Alvar Aalto chairs, Victorian jewellery, or vintage Chanel.
