Ariston Cafe in Litchfield is recognized as the oldest continuously operating restaurant on Route 66.
The restaurant was established in 1924 by Greek immigrant Nick Ariston and moved to its present Litchfield location in 1935. That move placed it directly on the newly aligned Route 66, allowing it to serve generations of motorists traveling across Illinois.
Ariston Cafe remains a family-operated business and is known for traditional American diner food, including sandwiches, steaks, soups, and desserts. Its long history reflects the close relationship between Route 66 and independent roadside restaurants.
The café is sometimes confused with other famous Illinois Route 66 eateries, especially Cozy Dog Drive In in Springfield and Lou Mitchell’s in Chicago. Those restaurants are historic, but Ariston Cafe is the establishment associated with the “oldest continuously operating” Route 66 restaurant distinction.
