Four teams representing the north, south, east and west of our city will battle it out on Thursday 5 July (7pm) in the Londoner Challenge. We've now selected those teams, and they include prominent London bloggers and Mastermind finalists.
The event takes place at the Museum of London and follows a University Challenge-style format. The teams face around 300 questions about London, written and hosted by M@ from Londonist. We have buzzers and picture rounds, a live score board and a bar. You might even be treated to the occasional Jeremy Paxman impersonation, if you're unlucky.
A few tickets are still available, at just £6 (£4 concessions). Get your tickets here.
The event finishes in time to watch the much-anticipated laser show to inaugurate the Shard building. So why not make a Londony night of it?
