Today's destination is the East End of London. Miriam Margolyes leads a trip around famous markets, historic pubs and some of the most notorious streets in London. The whistle-stop tour reveals the best way to eat jellied eels, brushes up on rhyming slang and meets a host of colourful cockneys from Fred the rag-and-bone man to 15-year-old wartime hero John 'Buster' Cain.
