Great British Menu - Season 13 Episode 42 -

Today the chefs must cook their fish courses but after some exceptionally high-scoring dishes in the starter round, everyone is desperate to deliver perfection in order to see off the competition. Once again the chefs present their innovative, witty or heartwarming creations, with lobster, mackerel, John Dory, turbot and hake among the dishes being scrutinized. The judges are joined by guest judge Chris Ogden, a revolutionary pioneer of robotic surgery. Specialising in prostate cancer, Chris is the most prolific prostate robotic surgeon at London's Royal Marsden hospital, performing up to 200 operations a year.
