Being an East London boy at heart I am partial to an occasional fix of café culture. Pellici's has been running since the start of the last century, to which me, my father and my father's fathers have all enjoyed its mix of tasty Italian/London grub and energetic atmosphere. If you're visiting, make sure you drop by, as it will provide a valuable, forever-depleting education into what East London is really all about.
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.
