This week, Tom travels the country to find out what makes the best Chinese takeaway and the trade secrets behind it, while Cherry explores the fascinating stories that shaped our communities as well as our palates. She discovers how the home washing machine kickstarted the takeaway and how Billy Butlin introduced Chinese food to the masses for the first time. Then, three of the nation's award-winning Chinese takeaways are invited to compete in a contest in the heart of London's China Town. Each is passionate about their own style of cooking but they all have very different ideas about what makes the best Chinese dishes. Each believes their version of the takeaway is the best but it is down to Tom and his expert judge, writer and chef Ching He-Huang, to decide a winner.
