Whopper price set for gourmet burger

LONDON, June 18 (UPI) -- A Burger King restaurant in London is offering customers the world's most expensive hamburger for the extraordinary sum of $190.

The Gloucester Road home of the whopper has concocted a special burger to benefit the Help A London Child charity, Britain's Sky News reported Wednesday.

The $190 sandwich features wagyu beef, white truffle, pata negra ham slices, crystal onion straws, modena balsamic vinegar, lambs lettuce, pink Himalayan rock salt, organic white wine and shallot-infused mayonnaise in an Iranian saffron and white truffle dusted bun.

"It sounds delicious," says celebrity chef Anthony Worrall Thompson. "The ingredients are very good and high powered."

Burger King's new burger beats the previous world record for the most expensive hamburger set by New York's Daniel Boulud in 1994. Boulud's DB Double Truffle Burger cost $130.
