Overview: London’s transport systems are iconic and ingrained on the Londoner’s psyche, not just as an essential part of life but part of the capital’s identity – and it’s London on the move that inspires Rachel’s cooking this time. She’s the guest at an unusual supper club where the food served up in a tube carriage, and she rolls her sleeves up to make sausage and mash for some hungry taxi drivers in one of London’s historic cab shelters. Back in her kitchen, Rachel creates a posh packed lunch and a healthy soup for busy people on the move, plus a sweet and colourful homage to the London Underground.
