Restaurant Critic Giles Coren and writer and performer Sue Perkins spend a week on a diet spanning the Regency Years of 1789 - 1821. With the wonderful Rosemary Shrager cooking for them at their country manor house, they enjoy the full trappings of the landed gentry. Dressing as a Jane Austen heroine, Sue is on a mission to find a husband, while Giles indulges in being a dandy.

In this programme they go back to the 1980s, the years of their adolescence. Living in a converted loft on the Thames, they sample the high life of a couple of yuppies. To a soundtrack of 80s classics including the Pet Shop Boys, Duran Duran, ABC and Billy Bragg, they power-lunch their way through the decade, knocking back champagne while talking loudly into their oversized mobile phones.

This time they travel back to the early days of the Roman Empire. Living in a splendid villa, Senator Giles dons a toga while Vestal Virgin Sue dresses in tunics and keeps the fires of Rome burning.
