I have listed the world's most expensive fast food below:

The World’s Most Expensive Pizza

The pizza is known as a “Pizza Royale 007” and it has a price tag of £2,150 or about €3,000. A dish prepared by a Glasgow based restaurateur, Domenico Crolla, The Pizza Royale 007 is made using an organic pizza base which is topped with edible gold sheets, fine cognac marinated lobster, champagne soaked caviar, sunblush tomato sauce, Scottish smoked salmon and venison.

The pizza was initially prepared for Mr Maurizio Morelli, an Italian lawyer in Rome, as a Valentine's gift to his wife. The pizza's proceeds went to the Fred Hollows Foundation, which aims to prevent curable blindness in developing nations.

The World’s Most Expensive Burger

The Four Seasons Hotel in Jakarta, Indonesia has created the pricey hamburger which costs a million Indonesian rupiah or approximately $110, and is thought to be the world's most expensive burger. The taste is a fusion of East meets West and the hamburger is made with a home-made onion-wheat bun and includes the finest Japanese Kobe beef. Toppings include wasabi mayonnaise and Italian Portobello mushrooms, it is served with an Asian pear and the French foie gras, french fries, and it may be washed down with a glass of wine.

The Kobe beef comes from the infamous Japanese Wagyu cattle breed raised on a special beer and grain diet and the livestock are massaged daily to in order to tenderize the meat.

The World’s Most Expensive Hotdog

The United Nations has sold what is known to be the world's most expensive hotdog in Stockholm's Norrmalmstorg in 2005 in an effort to raise funds for the United Nations' aid work. A pricey piece of sausage, placed in a roll with a selection of toppings and usual condiments was priced at 999 kronor or about $145 apiece.

The World’s Most Expensive French Fry

This very unique 'limited edition' french fry called the “Lincoln Fry” contains the profile of Abraham Lincoln and has appeared in a McDonald's ad in the 2005 Super Bowl. In actual fact, this french fry was used as a prop during the commercial, however it has since been auctioned on eBay and was sold to the Golden Palace Casino.

The proceeds of nearly $22,000 went to the Ronald McDonald House Charities, making the Lincoln Fry the world's most expensive iconic French Fry of all time.
