"Driving through Louisiana in 1953, Troy Smith discovered a hamburger stand that had installed an intercom system to speed up ordering. Troy thought the idea of ordering food from parked cars would be perfect for his Top Hat Restaurant in Stillwater, Oklahoma. He borrowed a bunch of cars from a friend who owned a used car lot and parked the cars in a row as a guide to form stalls around his restaurant. He wired an intercom system to the stalls and renamed his drive-in "Sonic" with the slogan "Service with the Speed of Sound." The new concept was a smash, and revenues for the redesigned hotdog and hamburger stand doubled during the first week. This recipe includes three terrific clones for the top-selling signature burgers served at Americas largest drive-in chain: the all-American Sonic Burger, the smoky Hickory Burger, or the spicy Jalapeno Burger. ..."
