Crazy about sourdough? You need to find the cavernous E5 Bakehouse located under the arches at London Fields train station. It is an artisan bakery and coffee shop and you can also get cakes and lunches. They even run bread making courses. If you follow them on twitter they will let you know when a fresh batch is out of the oven so you can rush across the park and catch their famous 'Hackney Wild' loaf before all the local trendies snatch it up!
