Hidden away in one of Greenwich Village’s most famed buildings, Trattoria One Fifth is far more than just another moody Italian restaurant in Manhattan.

Its storied walls have witnessed numerous notable events and social gatherings—from patrons toasting martinis while WWII soldiers paraded through downtown, to the ’30s supper club Number One Bar, which launched the careers of Dorothy Lamour and Paul Lynde, and the ’90s seafood restaurant One Fifth Avenue, where acclaimed chef Alfred Portale and Anthony Bourdain made their mark.
