If anywhere can pull off an urban\/suburban village fete in the middle of London, it's Bermondsey. There's a (very competitive) dog show, street entertainment, craft beer, a whole street of fabulous artisan market stalls and a poetry trailer. Tanner Street Park is full of food and drink traders and has a live music stage. It's a fabulous day out with something for everyone, so head over and have fun! Highly recommended.
