Galt Niederhoffer (center) celebrated the publication of her second novel, The Romantics, with a Chelsea rooftop party keyed to the book’s story: “It’s like a wedding reception in your mouth,” a publicist gushed about the spring rolls with peanut sauce that came by on one of the many platters passing through the crowd. (And, of course, it wouldn’t be a reception without pigs in blankets!) Guests were encouraged to dress like “slutty bridesmaids” and “lascivious groomsmen” for the event, but nobody (or very few, depending on which observer you asked) seemed to take the bait—as it was, the women who came in high heels found themselves treading carefully to avoid the gaps between the rooftop planks (not to mention the ventilation grills).
