"I'm sitting outside a café in Hackney in north London. When you close your eyes in Hackney (on a warm day!), you think you are in Vietnam because this part of the city smells of ginger, chilli and the other ingredients of Vietnamese food. My parents and I have lived in Hackney since we arrived here in 1976. We were refugees and I was only three. At that time, thousands of Vietnamese escaped from the communist dictatorship in Vietnam on small boats, and many came to live in London.
