The Diner was first brought to Elmira, NY and opened in 1941. Originally named “Vic’s Diner”, it was located at 220 Madison Avenue.

It was first owned and operated by Mrs. Kosloski. In 1946, the diner is sold to the last owner's brother-in-law Frank Niekras. In 1949, Joe Warakonski started working at the diner and took over the ownership and operation of the diner up until the closing on October 12, 1974.

The diner was purchased that same year by Arthur and Frances Sullivan and was taken to the Horseheads, NY location (where it resides to this day) and renamed the “Sullivan's Diner”.

The Sullivan family would go on to own and operate the diner until 2005.

From 2005 on too the current time, “Sullivan’s Diner” would become renamed and known as “The Diner”. New changes in ownership would see that The Silk City car would receive a full makeover, with care to retain the original woodworking and historic features. Modern updates to the kitchen area, and outside façade soon followed.

As of 2022, an expanded outdoor patio was added with a covered roof to allow for additional seating. Future upgrades will continue to be made to The Diner to ensure patrons can enjoy this historic dining experience for years to come!
