Over the next two nights the remaining twelve contestants are split into two groups and get their first taste of a professional kitchen when they have to run an entire lunchtime service. In this episode the first group head to Eneko in Covent Garden, London. This is Spanish chef Eneko Atxa's second restaurant and specialises in Basque cuisine. During a busy lunch service, the six amateur cooks are entirely responsible for serving the restaurant's menu to paying customers. Then it is back to MasterChef HQ for an invention test for John and Gregg. The contestants also discover that they must also impress renowned fish chef and two Michelin-starred Nathan Outlaw, who has picked his favourite ingredients which the contestants must cook with. After this challenge, one of them is sent home. Only the best five make it through to Friday's challenge - the gateway to the semi-finals.
