Semifinal day one

Overview

The four semi-finalists are sent to some of London's best restaurants to fine tune their individual cooking styles - before coming back to the studio to show judges John Torode and Gregg Wallace exactly what they've learnt. And they must then take on the challenge of being the sole caterers at an exclusive society dinner.
