A luxury hotel in Indonesia is offering the world's most expensive hamburger at $110, and 20 of the pricey burgers have sold since being introduced earlier this month at the Four Seasons Hotel. For perspective, a regular burger and fries in Indonesia's fast-food restaurants runs about $2.

AFP reports the 7-oz. burger is Japanese Kobe beef with wasabi mayonnaise and Italian portobello mushrooms on a homemade onion-wheat bun. It's served with Asian pear, French foie gras, fries and a glass of wine.
