The contest comes to an all-singing all-dancing climax with a banquet celebrating Britain's success in pop music at London's Abbey Road Studios. Ahead of the chefs is the challenge of cooking in a kitchen they don't know as well as having to scale up their dishes to provide the highest calibre of dining. Plus, in a Great British Menu first, they have to adapt their dishes for vegetarian diners. Those attending include Andrew Ridgeley, Martin Kemp, Keisha Buchanan, Peter Hook and Gary `Mani' Mounfield. Last in the series.
