Lord Sugar and his candidates meet at Mercato Metrapolitano in Mayfair, a former church now offering artisan food and drink from around the world. Whetting the candidates' appetite for this week's task, the peer reveals they will be creating and branding a new non-alcoholic drink, before hosting a launch event where they will pitch and sell their product to leading retailers. One team plays it safe with flavours but struggles to replicate a key ingredient, while a fruity late addition in the other side's drink isn't to everyone's taste. As usual, Karren Brady and Tim Campbell act as Lord Sugar's eyes and ears on the ground.

The teams' next task is to create their own computer game and pitch their concept to a panel of hugely successful games investors.
