2007 October 26, Matthew Preusch, “Cleared for Lunching: The $100 Hamburger”, inNew York Times[1]:
It’s called hunting the$100 hamburger — “$100” referring to the cost of fuel — sort of the aeronautical equivalent of lazy Sunday drives in which the destination isn’t as important as the pleasure of getting away.
Used other than figuratively or idiomatically:seehamburger.
2010, William Poundstone, quoting Brandon O'Dell,Priceless: The Myth of Fair Value (and How to Take Advantage of It), Farrar, Straus and Giroux,→ISBN,page159:
Daniel Boulud has a restaurant that serves a truffle and Kobe steak hamburger for $100[…] It's to make everything else on the menu look cheap by comparison. Someone sees a$100 hamburger on the menu, and they can look at a $50 steak and see it's a bargain.
