How well do you know London? Matt Brown will take you on a tour of parts you might not be aware of - from the deepest catacombs to the highest rooftops.  For 12 years, Matt has been a professional explorer and chronicler of the capital as editor (now editor-at-large) of 'londonist.com' . He'll begin by describing the genesis of Londonist - a website that sprang from hobby to successful business. The site has published almost 50,000 articles about London and now has 1.3 million twitter followers. 

Matt will then share stories from some of his most intriguing site visits. Find out what happens behind the lights of Piccadilly Circus; how to stand on the weather vane of St Bride's; the secret rooms and relics of St Paul's; and how to dress yourself in the morning when your day includes a trip down the Northern Outfall Sewer AND the press launch of a new sherry bar. 

Throughout, the talk will be peppered with revelations from Everything You Know About London Is Wrong -- Matt's myth-busting guide to the capital which will be available for sale on the night.

The evening will finish with drinks, mince pies and other Christmas treats.
