According to the Vaad Harabonim of Queens (VHQ), they are no longer giving the kashrut supervision for Subway located at 141-24 Jewel Ave in Kew Gardens Hills, Queens, NY.
It seems that over the past couple years, the various “Kosher” Subway restaurants in the NY area have been dropping like flies. The Kosher Subways on Central Ave (Cedarhurst), Water Street (Manhattan), Avenue J (Brooklyn), have all closed in the past year or two.
Perhaps this was a fad.
