Calling all batter fiends: Legendary diner Breakfast Club are challenging Londoners to eat their way through a stack of 12 pancakes in 12 minutes or less. If you win, your meal is on the house. If you lose, you’ll pay the full price (£20) with all profits donated to local charities. There's no need to book, just rock up to any Breakfast Club cafe at any time on Feb 28 and try your hand at the challenge. All entrants get a free keyring.
