…Some restaurants use what researchers call decoys. For example, they may place a really expensive item at the top of the menu, so that other dishes look more reasonably priced; research shows that diners tend to order neither the most nor least expensive items, drifting toward the middle. Or restaurants might play up a profitable dish by using more appetizing adjectives and placing it next to a less profitable dish with less description so the contrast entices the diner to order the profitable dish.
Research by Brian Wansink, director of the Food and Brand Lab at Cornell University and the author of “Mindless Eating: Why We Eat More Than We Think,” suggests that the average person makes more than 200 decisions about food every day, many of them unconsciously, including the choices made from reading menus.
Menu design draws some of its inspiration from newspaper layout, which puts the most important articles at the top right of the front page, where the eyes tend to be drawn. Some restaurants will place their most profitable items, or their specials, in that spot. Or they place a dotted outline or a box around the item, put more white space around it to make the dish stand out or, in what menu researchers say is one of the most effective tools, add a photograph of the item or an icon like a chili pepper.
Unless a restaurant wants to frighten its customers, the price should always be at the very end of a menu description and should not be in any way highlighted.
A study published in the spring by Dr. Kimes and other researchers at Cornell found that when the prices were given with dollar signs, customers — the research subjects dined at St. Andrew’s Cafe at the Culinary Institute of America in Hyde Park, N.Y. — spent less than when no dollar signs appeared. The study, published in the Cornell Hospitality Report, also found that customers spent significantly more when the price was listed in numerals without dollar signs, as in “14.00” or “14,” than when it included the word “dollar,” as in “Fourteen dollars.” Apparently even the word “dollar” can trigger what is known as “the pain of paying.”
Mr. Rapp, of Palm Springs, Calif., also says that if a restaurant wants to use prices that include cents, like $9.99 or $9.95 (without the dollar sign, of course), he strongly recommends .95, which he said “is a friendlier price,” whereas .99 is “cornier.” On the other hand, 10, or “10 dollars,” has attitude, which is what restaurants using those price formats are selling.
A dash or a period after the number appears to be more of an aesthetic choice than a psychological tool, according to one of the authors of the menu pricing study, Sybil S. Yang, a doctoral student at Cornell. Numbers followed by neither a dash nor a period are most common.
…Other research by Dr. Wansink found that descriptive menu labels increased sales by as much as 27 percent. He has divided descriptions into four categories: geographic labels like “Southwestern Tex-Mex salad,” nostalgia labels like “ye old potato bread,” sensory labels like “buttery plump pasta” and brand names. Finding that brand names help sales, chains are increasingly using what is known as co-branding on their menus, like the Jack Daniel’s sauce at T.G.I. Friday’s and the Minute Maid orange juice on the Huddle House menu, Dr. Wansink said.
Dr. Wansink said that vivid adjectives can not only sway a customer’s choice but can also leave them more satisfied at the end of the meal than if they had eaten the same item without the descriptive labeling.
