The World's Most Expensive Food

More than half of London's ten-million-pound properties are now owned by foreign money. The most exclusive food suppliers must adapt and fight harder than ever to win over this lucrative market.

Competition for the attention of the new super-wealthy is driving innovation. When clients have eaten in all the best restaurants, it's exclusivity and the story behind the food that matter.

While most people buy their food in the supermarket, Britain's growing numbers of billionaires use a private network of luxury food suppliers. This documentary sees how they cater to their super-rich clients in a world untouched by austerity. They include a catering company who charge more than £1,000 per head and a Welsh cattle farmer who massages his Japanese Wagyu cows as well as giving them beer to drink (to improve the characteristic marbling effect in their beef). The documentary also meets etiquette expert William Hanson, who travels the world teaching super-rich foreign clients how to negotiate the minefield of a dinner party.
