The candidates are summoned to the National Portrait Gallery, where Lord Sugar instructs them to organise an exclusive late-night event at two of London's biggest tourist attractions - the London Aquarium and Madame Tussauds. In under 36 hours, each team must organise and host an event to remember, keeping an eye on profits but also pleasing the punters. From setting up refreshments and entertainment to making sure they sell enough tickets to fill their venue, both teams have a challenge on their hands.
