45 Park Lane, Dorchester Collection

What the classifiers highlight

The Dorchester's art deco sibling on Park Lane holds just 45 rooms, one a penthouse, each looking onto Hyde Park. Thierry Despont's warm, chrome-and-leather interiors hang works by Damien Hirst, and guests borrow the spa next door at the Dorchester itself. MICHELIN awards Two Keys and houses Sushi Kanesaka inside; Wolfgang Puck runs the steakhouse, CUT.
