London's various food and drink festivals are usually over-hyped and over-priced, but I love them all anyway. Just give me a fistful of tokens and a map and I'm happy for hours.
With that in mind, has anyone been to the Great British Beer Festival before?
Is it worth a visit, given that tickets seem to be relatively cheap?
