Another London based blue here, I live in Wandsworth where every lid is a Chelsea fan so I'm always wearing Everton gear to get in their faces. Lived down here for years tbh
The famous 3 kings is good but most pubs show the Sky games so if Everton are on it'll be on in most pubs. I can remember being in the Grand Union pub in Twickenham when we played Chelsea in the Carling Cup a few years back and lost 2-1, when Yak put us 1-0 up I went bat **** mental and I was literally the only blue in the joint
I don't actually know any blues down here so if anyone wants to meet up for the derby at the 3 kings I'd be up for it, the derby always attracts a crowd there, mainly Cockney Kopites who've never been to Liverpool in their lives
