Hi,
My sister went to the Illinois State Fair over the weekend. She followed my advice to buy her food at the agricultural association tents: Beef, Lamb and Pig. It is usually the best fair food bargains as well as simply good food.
My sister did explain the barkers at the lamb tent were shouting out to people to try their "Gyros" pronounced similarly to gyroscope. It's been a long time since I made that mistake. Though I do recall reading long ago in the Chicago Tribune when the first Gyro vendor opened in Chicago, they were in the telephone classified yellow-pages under Gyroscopes.
Regards,
