Last weekend at the Culinary Historians Symposium, there was a lecturer from U of I Champaign who is a psychologist working in the Ag area, which covers foods. They conduct a restaurant where they do human studies. They serve the exact same menu to all diners but alter presentation to different diners, then weigh the leftover waste on the plates and review exit surveys.
An example of a head spinning dining experience they concoct:
Buy the cheapest wine, then relabel two ways: Cabernet from South Dakota as well as Cabernet from California
Diner's are presented with a complimentary glass of wine from one of these states. Later, those who had the South Dakota wine, left more food on their plates and their reaction to the entire meal was so-so. Those who had the California wine, left less food waste and were quite thrilled how the quality of the wine enchanced the entire meal.
Remember, this was el cheapo wine --- so they objectively proved their are psychological factors involved in your perception of food and wine.
On another occasion, they served the same non-descript chocolate cake to all diners. For one group, it was referred to as Imported Belgium Double Chocolate Cake and for another group simply Chocolate Cake. This cake was nothing special edging on stale. Those who received the Belgium (zipped up name) cake were quite eager to show appreciation and praise. Those who simply received the Chocolate Cake without the suggestive emotional charge were considerably less enthusiastic.
I am just dying to go to this restaurant, which is open only one day a week in Champaign. I want to bring some people for this bit of culinary head games, so I don't want to blow it by it becoming an 'open' secret.
Fortunately, I have a pool of friends who don't read LTHforum. com unless I specifically point them somewhere. So this secret is just between us!
