TV shows have really just honed in on our fascination with all things food related with yet another documentary on the topic, this time, about the world's most expensive food. We meet the suppliers who provide the food to some of London's richest residents, as well as a Welsh cattle farmer who massages his Japanese Wagyu cows, as well as giving them beer to drink, all to improve the characteristic marbling effect in their beef. There's also etiquette expert William Hanson, who travels the world teaching super-rich foreign clients how to negotiate the minefield of a dinner party. Pfft. Give us a three-in-one any day.
