Top restaurants use these simple techniques to leave you thinking about their food

Business Insider spoke with Professor Charles Spence, Head of Crossmodal Research Laboratory at Oxford University and author of “Gastrophysics, The New Science of Eating,” about what techniques restaurants use to make sure customers remember their dining experience. 

He said: "One thing [restaurants might do] is to surprise the diner with a little amuse-bouche. Something you weren't expecting. Those kinds of surprising treats will stick in memory more than things they were expecting to taste.

"You might also switch from a traditional 3-course menu to a tasting menu with lots of small plates of food. Because each time you bite into that new dish, that's another "sticky" moment that may reside in memory for longer."
