MasterChef: The Professionals (2008) : 7x16

It's the semi-finals. Firstly, Marcus and Monica send the semi-finalists to London's Knightsbridge to work in service under one of the country's greatest fish chefs - Nathan Outlaw. Nathan earned his first Michelin star at the age of 25 and now holds three in Cornwall and one at Outlaw's, where the semi-finalists must deliver. First, Nathan shows each chef a dish from his menu, which they must take charge of in the lunchtime service. Their cooking skills, timing and judgement must be absolutely spot-on if they are to do justice to the delicate modern seafood dishes that have earned Nathan his award-winning reputation.
