The Clamshell previously was located in the Iowa towns of Mount Pleasant, Mount Union, and Danville. At Danville it was known as the Cracker Box Diner. Rescued from a scrapyard by Tom Keller and Mel Gross, the diner was moved to Muscatine and restored. In 2004 it was sold to Tom and Ann Meeker and moved to its present location.
