Yo Kool, a frozen yogurt shop, opened for business in early June at York River Crossing Shopping Center, Hayes.
Yun Bo Yang owns the business with his son, Johnny, a sophomore at George Mason University. They reside in Williamsburg.
Johnny Yang said the store serves a dozen flavors of frozen yogurt at a time, rotating flavors like dark chocolate, mango, strawberry-banana and cheesecake. Customers can pick from three size cups and fill them with one or more types of yogurt and a wide range of toppings (fresh fruits, nuts, candy and cereals). Also, bottled soda and water are sold. The cups are weighed and customers pay by the ounce.
