"Our guests want it, so we still buy it," said Jason Kallert, Le Cirque's executive sous chef. "Our customers will pay whatever we charge."
And customers with no budget — mainly celebrities and other wealthy food lovers — are exactly the kind of following white truffles have attracted.
Kallert said some of the biggest fans of Le Cirque's truffle dishes are the restaurant's celebrity clientele. In fact, white truffles are winning over the hearts of celebs who in years past have indulged in other luxury treats — like caviar.
Just this week, rock star Marilyn Manson was spotted indulging in white truffle-sprinkled lobster in Las Vegas, according to People Magazine.
"The Sopranos" star Lorraine Bracco has also been known to be a huge truffle fan.
"It's a delicacy," Bracco told ABCNEWS.com. "Some people really love caviar. I hate caviar. Some people love foie gras, and some people love their truffles."
Bracco, who described the taste of white truffles as "strong" and "pungent," said that her favorite way to eat truffles is actually pretty basic.
"My favorite is as simple as it comes: pasta, with olive oil and truffle shaved on the top," said Bracco, who added that she believes the weak U.S. dollar is the chief reason truffle prices are so high. "I like it really, really simple."
Simple at $4,000 a pound, that is.
