In the Caribbean, one of the largest floating kitchens is dishing up fine dining for over three and a half thousand cruise ship passengers. The tireless staff on the Regal Princess work across 20 huge galleys to provide round-the-clock food that is just as stunning as the holidaymakers' tropical surroundings. Launched in 2014, the 1000ft long Regal Princess is a true leviathan. And with 3,700 passengers and over 1,300 crew to feed, it has an equally giant cooking operation. Every week these kitchens get through a whopping 140 tons of food. We join the ship on a seven day tour of the Eastern Caribbean. With just ten hours to stock up 15 massive provision rooms, the kitchen team can't miss a single item. As well as cooking for guests in 16 different bars and restaurants spread over 17 decks, this week the team also has to prepare a monster beach barbecue in the Bahamas.
