A Speakeasy Bar.

Once you have found the discreet door, you descend down some dark stairs into what appears to be a 1920s office before being interrogated by a detective. He finally pulls a lever, a bookcase rotates and a bar is revealed. Welcome to Evans & Peel Detective Agency, part of the speakeasy trend that has gripped the capital. In this haunt, savvy visitors can discover the illicit thrill of Prohibition bars – without the risk of being raided by police.

Kyoto Garden. Central London is full of still, small oases of calm, if you know where to look. Visit the Kyoto Garden in Holland Park, which boasts a waterfall, koi carp, a stone bridge and roaming peacocks. The garden was donated by the Chamber of Commerce of Kyoto in 1991, and is a much-loved gem.
