Ariston Cafe...Litchfield, IL The Ariston Cafe was founded by Pete Adam, a Greek immigrant, in Carlinville, Illinois in 1924. The original cafe was located on Route 4, the predecessor of Historic Route 66. In 1929, the Cafe was relocated to Litchfield, Illinois and moved into its present location on Route 66 in 1935. We believe the Ariston Cafe to be one of the oldest, if not the oldest restaurant on Route 66
