London is home to more billionaires than any other city on the planet and like all of us, they require sustenance to survive. However, while most of us buy our groceries at the supermarket and mere millionaires consult the Michelin Guide when selecting a restaurant, the ultra-wealthy retain the services of a private network of luxury food suppliers. THE WORLD'S MOST EXPENSIVE FOOD is a delightful British mini-series that follows several renowned food purveyors who cater to the nouveau riche. From supplying the world's best caviar to creating decadent meals for private jet users, these luxury vendors will go to any length to source, import and prepare the world's most expensive food and drink for their clients. In this rarified world, the finest ingredients just aren't enough: it's the story behind them that counts.
