Just seen this on the BBC: BBC News - Digital bar flies: Pub where everybody knows your game
It's a pub for gamers called The Meltdown in Islington. Looks worth a trip and it's just a couple of minutes walk from a tube station :)
Their Facebook page is here: https://www.facebook.com/MeltdownLondon
Guess where we shall be taking the guys at BETT 2014!
