The final week continues, and the heat is on as the three celebrity finalists face their most gruelling task to date. The celebrities are split up, with each finalist cooking a lunchtime service in a top London restaurant to enhance their skills and iron out their particular weaknesses.

Sir Terence Conran's landmark Bibendum, innovative French restaurant Le Pont de la Tour and modern tapas-inspired bar and restaurant Salt Yard put the finalists through their paces. As well as working to each of the head chefs' exacting standards, the celebrities are asked to recreate one of their signature dishes. Will they stand the pressure of the professional kitchen?

Next, they head back to the MasterChef HQ to illustrate just how much they have learnt. The challenge is to cook one sublime dish from the restaurant menu to perfection, in just one hour. Only one contestant can be crowned Celebrity MasterChef Champion 2011.
