People associate the luxury of an expensive restaurant with sexual pleasure, while eating tasty food in a cheap diner is more likely to be compared with drug addiction and physical trauma, scientists found.
Diners at luxury restaurants praise the "orgasmic pastry" and "seductively seared foie-gras", whereas patrons of less salubrious establishments justify their food choices by claiming "the fries were like crack" or that they are "addicted to wings".
The findings come from a language analysis of more than 900,000 online reviews of 6,500 restaurants across seven American cities. The study compared the wording people used in giving good and bad reviews, as judged by how many stars they gave to a restaurant.
"The more expensive the restaurant, the more likely you are to describe the food in terms of sex," Dan Jurafsky, professor of linguistics at Stanford University in California, told attendees at the American Association for the Advancement of Science convention in San Jose.
"If you like a very expensive restaurant, you use words like 'orgasmic', 'sensual', 'sexy' - and my favourite phrase was 'a very naughty deep-fried pork belly'," Professor Jurafsky said.
