Shake's Frozen Custard, Inc. operates more than 25 (mostly franchised) 1950s rock-n-roll themed Shake's Frozen Custard locations in eight central and southern US states, including Alabama, Arkansas, Florida, Indiana, Kansas, Missouri, Oklahoma, and Texas. Of course shakes and malts are on the menu, but you also can find sundaes, cones, and fruit drinks. Founded in 1991 in Joplin, Missouri by Don and Bebbie Osborne, the company began franchising in 1999.
