Beer Forum

So I'm planning on going to the Great British Beer Festival this year in London (August 4-8): http://gbbf.camra.org.uk/home
Have any of you chumps ever been before or heard anything about it?

I'll be there hopefully, considering I'm only a few hours away on the train!!! I'll have to see if I can get a BN shirt of something to wear.

I've been a couple of times before, its always a good festival, but not a cheap festival!
