Here is a photo of the restaurant at the ex-New York Central's Valhalla station, now called Valhalla Crossing Restaurant in Westchester County, NY (just north of White Plains). It is located off the Taconic Parkway by the Kensico Reservoir along the Harlem Division of Metro-North Railroad. My friend was involved in the original construction of the restaurant and was able to salvage some vintage sleeping car woodwork and used it to create a Pullman-like bedroom for himself.
While I grew up in Westchester County , I never found time to visit, so far.
