It's the last semi-final and three of the remaining chefs are in close competition for a place in finals week. For their first challenge, they are sent to cook at one of the UK's most famous restaurants - the two-Michelin-starred Le Manoir aux Quat'Saisons in Oxfordshire, home of legendary chef Raymond Blanc OBE. Here, executive head chef Gary Jones, who has worked as executive chef at Le Manoir for 22 years, takes the three semi-finalists into his kitchen for the ride of their professional lives.
