This self-serve River North fro yo shop, located in space formerly occupied by a Cold Stone Creamery, offers a rotating selection of 25 flavors. Alpine vanilla, tart, coconut, peach, strawberry, cappuccino and other types are served; some no-sugar varieties are also available in flavors like raspberry. Just grab a cup, dole out your dessert and finish it off with any of the 30 available toppings--kiwi, mango, cookie dough and other sweet treats, for $0.45 an ounce. (Royal Berry also plans to offer cupcakes and other items from a local bakery in mid-August.) Hoping to beat the heat and finish your dessert indoors? The eatery's stainless steel tables, imported from Europe, offer seating for about a dozen customers.
