Slightly north of SoHo, on Eighth Street, a bar/restaurant called One Fifth (at 1 Fifth Avenue) offered a seductive counterpoint to SoHo's industrial chic, having installed the Art Deco fittings of a decommissioned ocean liner, the Cunard Line's RMS Caronia.

Later they restored the historic Keen's Chop House in midtown, and opened the NoHo Star, still a lively scene. One Fifth drew a multi-generational audience of artists, journalists, poets and downtown celebrities (1975-ca. 1986); it was also a frequent venue for Larry Rivers's East Thirteenth Street Band.
Kiki Kogelnik died in 1997 but her art was later featured on an Austrian stamp in 2003:
