Sweet Frog’s frozen-yogurt flavors go beyond the norm. In addition to cookies ‘n’ cream and raspberry pomegranate, the lineup of 75 varieties includes mango, cake batter, and chocolate caramel. Patrons can sprinkle on toppings such as fresh fruit and candies, then savor their confetti’d confections in the lime-green-and-pink restaurant. Smiling frogs and funky white hanging lamps give the stores an air of fun, but founder Derek Cha is interested in giving more than that to the community; through Sweet Frog, he sponsors children in need and dispatches frog mascots to those who need encouragement.
