As a culinary expert with a deep knowledge of the food industry, I can tell you that the title of the most expensive burger in the world is often a subject to change as restaurants and chefs continually push the boundaries of luxury dining. However, as of my last update, the record for the most expensive burger was held by the Fleur Burger 5000, created by chef Hubert Keller of San Francisco's Fleur de Lys restaurant.

This extravagant burger is made with the finest ingredients, including a Kobe beef patty, foie gras, and truffle. It's served with a side of chips and a bottle of 1995 Château Pétrus, one of the most expensive wines in the world. The price tag for this luxurious burger is a whopping $5,000, making it the most expensive on record.
