Knockout Week continues as the remaining 11 contestants are split into two groups and get their first taste of professional cooking when they have to run an entire lunchtime service on their own. In this episode, the first group head to Typing Room, a London restaurant over seen by Lee Westcott, a protégé of Jason Atherton and Rene Redzepi's Noma. During a busy service, the five amateurs are responsible for serving up every dish on the menu to paying customers. Who will falter as they cook in a completely unfamiliar and demanding environment?
