The Worlds Most Expensive Food

I was approached by Channel 4 to take part in a documentary on following elite suppliers of the worlds most expensive food. I was asked to what lengths would chefs need to adapt to win over foreign billionaires? £5000 a shot of whiskey, £100 a plate of barnacles and £300 for a cup of coffee?

"Go big or go home!' is the opening gambit of one of the wealthy subjects of the show.
