C A Midtown restaurant will sell a $250 hamburger — an umami bomb comprised of Kobe beef, foie gras, crispy pancetta, white truffles and caviar. Ketchup and mayonnaise are complimentary. The Indulgence Burger at Beer & Buns, which will open later this month in The Court Hotel, is the latest mound of beef hoping to land the title of “most expensive burger” in the city. "We thought about charging $999 for it, but realized no one would buy that," says Abigail Tan, an executive with the hotel company. "For $250, someone may buy it and split it up." There’s certainly enough flavor for two — and that’s part of the problem. Chef Wisit Panpinyo’s concoction is so rich with pancetta and foie that you don’t even taste the caviar. It's not the first time burger prices have been overcooked. Serendipity 3 offers a $295 patty with truffles, caviar, gold and even a diamond toothpick — but a portion of the price is set aside as a donation to the Bowery Mission. Two years ago, the 666 Burger food truck sold a “Douche Burger” of lobster, caviar, truffles, foie gras and gold leaf for $666. But the truck is closed until May. The original expensive burger was created by chef Daniel Boulud in 2001, when her combined foie gras and ground short ribs at db Bistro Moderne. The dish is still on the menu for $32 — but the truffle version is $140. 59.Which word can be replaced of the word "comprised"in the first paragraph?
