We're keeping a close eye on L.A.'s favorite fauxen yogurt chain PInkberry; it's already hawking its addictive mixture of air and chemicals and mouse excreta at four locations in the city. Eater mentions today that Pinkberry's fifth outpost will open soonish near the Columbia University campus at 112th and Broadway. Good news for Columbia frosh, because nothing goes with Thinking Sexuality Transnational class like an ounce of swirly fat-free frozen chemicals, if only because Columbia students hate their bodies and theirselves.
