Simon Rimmer challenges five couples with business ambitions to manage a restaurant for one day. The staff and diners have been arranged for them, but they will have to create a menu and serve it themselves. The diners will choose how much money to pay for their meal: 25 pounds, 10 pounds or nothing. The couple who make the most money will get to keep all the money made that week: which could be as much as 5000 pounds. This time, the Head Chef falls out with the porter.
