Big Kitchens explores the mind-boggling logistics, colossal cuisine and extraordinary characters behind the world's biggest, most extreme kitchens and restaurants. Each episode visits a different restaurant to reveal its secret workings – from the world's biggest truck stop to the US Army's largest dining area…from a jumbo jet catering facility, to the biggest kitchen cruising on the open ocean. We visit these monster kitchens on one of the busiest days in their calendar when they cook their biggest banquets.

We find out what makes each kitchen tick – the larger than life characters – the cooks and chefs; the bespoke technology behind the cooking; the dazzling logistics involved in seating so many people; the overwhelming volume of ingredients, and the power needed to cook it all. We discover the secrets behind their finest dishes and uncover the facts and stats that keep each extreme restaurant running.
