$100 hamburger

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.

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.
