The world's most expensive pizza costs $12,000 and takes three full days to make in your own kitchen.

Chef Renato Viola created this luxury meal called the Louis XIII in Salerno, Italy. Even though it costs a fortune, the pizza is only about 8 inches wide, which is the size of a small personal pizza. The long 72-hour wait is mostly for the dough, which has to rest for three days to get the perfect texture.The toppings are what make it so pricey. It features three kinds of super-expensive caviar, which are rare fish eggs, and organic buffalo mozzarella cheese. It also uses a very special pink salt collected from underground water in the Murray River in Australia.When you order this pizza, you aren't just paying for food. A master chef, a second chef, and a drink expert come to your home to serve you. They even bring limited-edition plates and cutlery to use. The meal is served with a famous cognac that costs about $3,000 a bottle on its own.
