Most frozen-yogurt shops aren’t embellished with wooden accents and soft, stylish lighting. Then again, most shops wouldn’t dub themselves a “frozen-yogurt boutique.” But YoArt, the sister store of Frannie’s Goodie Shop boasts both the decor and upscale sweets to do just that. Stamped with a Live & Active Cultures seal from the National Yogurt Association, each of its yogurts mask healthy, digestion-aiding probiotics behind the veneer of a frosty dessert. The self-serve bays are loaded with 12 flavors each day, including Ghirardelli Chocolate, Very NY Vanilla, and Greek Black Cherry as well as non-dairy sorbet and fresh gelato. More than 80 toppings from an island and wall-affixed dispensers cascade over chilly peaks of sustenance, including freshly whipped cream, champagne cordials, and 21 colors of M&M's.
