We have met the enemy, and he is acidophilus: Yogurtland and Orange Leaf shops are set to open on Amsterdam Avenue in the next month or so, bringing the total number of frozen-yogurt shops on the stretch between West 72nd and West 86th Streets to eight. The situation has gotten so serious that locals have dubbed the neighborhood “yogurt alley,” and a franchisee of an incoming shop has a reasoned approach to the glut, arguing that different frozen-yogurt shops actually serve different demographics — the “richer, creamier” stuff at Orange Leaf is best suited for “young families,” apparently. In other news, Pinkberry is best for aging spinsters, and 16 Handles is most appropriate for reformed robber barons, or something. [DNAinfo]
