Hosted by the Museum of London, The Londoner Challenge is a quickfire multimedia quiz with around 300 questions about the capital, all set by the Londonist.
There will be two semi-finals, followed by a final. There will be buzzers, and there may be the odd Jeremy Paxman impersonation.
Teams are captained by London bloggers who are joined by carefully hand-picked teams! Let's hear it for North London's team, captained by Jonathan Turton of West Hampstead Life.
Tickets are £6.
