Shh... this week's Time Out magazine is all about London's biggest secrets - from an artist's treasure trove to a house stuck in the 1900s. We've also got top tips for nabbing a cab in rush hour and getting served in a busy bar. Elsewhere, we talk to 'Pan' filmmaker Joe Wright and 'Grand Designs' presenter Kevin McCloud. We tell you how you can meet hundreds of dogs in real life and where to find London's best flat white. Plus, three Syrians who've made London their home talk to us about the refugee crisis.
