Jahn's Ice Cream Establishment

July 23, 2007. Jahn's, on 117th Street off Myrtle Avenue in Richmond Hill, is 100 years old this year (2007). I paid them my first visit in 1955. It seems hardly to have changed since then. Update -- Jahn's closed on the Saturday after Thanksgiving, 2007! The Jahn's in Jackson Heights, Queens, is the only one left now.
