Home of the Lonely Street, Concrete Jungle and other house cocktails named after iconic songs collected in the 'Savoy Songbook', the seriously dishy American Bar is a London icon, with soft blue furniture, gleaming art-deco lines and live piano jazz from 6.30pm nightly. Cocktails start at £20 and peak at a stupefying £5000 (for the Sazerac, containing cognac from 1858).
Named for serving 'American-style' drinks (now known as cocktails), it's the oldest cocktail bar in London. The dress code is smart casual.
