Jamie Olivers restaurant, Fifteen, made popular by Olivers TV show on which he trained disadvantaged youngsters to become chefs, has been slammed by the public. According to the new Hardens London restaurant guide 2005, which surveyed 7,000 ordinary restaurant goers, Fifteen was voted by over 50 percent of the people as the most overpriced. Co-author Peter Harden said: Thats virtually unheard of. Other descriptions included amateurish and seriously taking the piss. Quite surprising really, considering the cheap labour scheme.
