Painted berry pink, tangerine orange, and mint green, even the walls at Sweet Tart Frozen Yogurt look good enough to eat. Along a glass-tiled wall, customers pull levers to fill their cups with their choice of sweet or tart yogurt flavors, inspired by fresh fruits or popular desserts. Next, they move to the gleaming-white toppings bar, where silver basins overflow with fruits, candies, and nuts waiting to be sprinkled atop peaks of yogurt so they can slide down them on tiny little skis. There are no rules here, so patrons can come up with their own combinations, whether they top cake-batter yogurt with peanut-butter cups and chocolate sauce or blueberry-açaí-banana yogurt with brownie bites and butterscotch.
