Delmonico’s is now serving a cocktail that pays homage to a pair of spirits whose story is tied with the 181-year-old landmark restaurant. According to the New York City spot, the Vandevroot sisters were the daughters of a wealthy and controlling father who rarely let them leave their home. One of two places the sisters were allowed to visit without a chaperone was Delmonico’s, which, at the time, had been the only restaurant that permitted women to dine without the supervision of a male figure. Their father eventually drove away all of the sisters’ marriage prospects, fearing their suitors only wanted money, and the sisters died unmarried in the 1860s. As the story goes, the spirits of the Vandevroot sisters still haunt Delmonico’s at night, looking for husbands. As a nod to this eerie tale, the restaurant is now offering “The Suitor Seance” Martini — a pumpkin spice martini, crafted with vanilla vodka, pumpkin liquor, Cointreau and star anise — for $16.
