Did somebody say free beer?
That's right, a mystery brewer is giving away free pints across the capital. The brewery is keeping its identity a secret, as they want people to rid themselves of any preconceptions they might have and focus on how the beer tastes.
You can register for your free beer online, and then redeem it at one of over 200 London pubs on Thursday 26 April.
Once you've thoroughly quaffed the drink, try to work out who might be behind it. We recommend placing a bet with your mates over which brewer came up with the idea. Then, not long after you finish off your pint, you'll get a text revealing who the brewer is. What should you bet? Well another pint, of course. That way, if you guess correct, you can get two free beers for the price of none.
