New York City restaurant Seredipity 3 unveiled the world's most expensive hamburger, Le Burger Extravagant, this week.

Le Burger Extravagant sells for $295.00 (£186.52).

Made from white truffle butter-infused Japanese Wagyu beef, the burger is topped with James Montgomery cheddar cheese, black truffles and a fried quail egg.

It is served on a gold-dusted campagna roll spread with white truffle butter, and the roll is topped with a blini, creme fraiche and caviar.

Serendipity 3 is a popular Manhattan restaurant, and has been featured in several films, including 2001's romantic comedy Serendipity.
