As South Africa celebrates the 100th anniversary of the birth of Nelson Mandela, the Travel Show's Lucy Hedges heads to Johannesburg to discover how the city is reinventing itself and to meet Mandela's personal chef, who cooks up a dish that was one of Mandela's favourites. Lucy's next stop is Cape Town, where she visits the site of the historic speech Mandela gave when he was first released from prison. She then meets the young ballroom dancers who are helping to break down barriers between black and white.
