Amanda Hess visited the Museum of Ice Cream’s New York pop-up, the Rosé Mansion, Candytopia, Color Factory, 29Rooms, and even a preview party for the upcoming Museum of Pizza. “I realize that I have a ‘fun’ job that it’s annoying to complain about: Oh no, I have to drink free wine and eat ice cream. But as my summer of pop-ups dragged on, I began to dread my evenings. What began as a kicky story idea became a masochistic march through voids of meaning. … And yet, the ‘experience’ has emerged as among the defining fads of my generation.”
