The Best City for Hotel Bars: London

Wave down the wooden trolley, rolling by these marble tables since the 1850s, at the Connaught Bar. Bartenders in three-piece suits stir martinis made with Italian Gancia Dry vermouth, served here exclusively. the-connaught.co.uk.

If you’re catching London on a sunny day, opt for a terrace table under striped awnings at the Oscar Bar in the Charlotte Street Hotel, designed by Kit Kemp, and sip a Lady Charlotte (Bombay gin, maraschino liqueur, egg whites and apricot puree). firmdalehotels.com.

At the Savoy’s American Bar, pair the White Lady—a 1920s hotel original made with gin, Cointreau and lemon juice—with views of the River Thames. fairmont.com.
