Great selection of books and magazine with a big focus on rare. out-of-print books Japanese photography. Can sends hours in this little shop. I'd try to avoid on Market day (Saturday) if you want to have a good look as it can get a bit busy for such a small space.
This is one of my favourite places in the whole of London.
Cernamic, run by Nam and Susi, they offer some fantastic workshops and at a very affordable price. They have really cultivated a welcoming environment, full of lovely people and a place to share and recieve knowledge.
I can't pass without dropping in, Orcs Nest is a small independent boardgame, D&D etc store that's been around forever(1987)... and has the best logo. Good selection of games for younger kids too.
The thing I love most about London is the juxtaposition of urban and rural, and nowhere is this better illustrated than in Lea Valley Park. A genuine wilderness where I’ve seen everything from ponies, to a rogue Costco outlet, and all less than 20 minutes from my front door.
