Dallas-based frozen yogurt chain Red Mango, in the news pretty often these days, has awarded development agreements for more than 70 additional locations in some 20 states. One of the most recent deals will see the opening of five stores in the Atlanta area. The sweet-treat chain specializes in “fro-yo” beverages as well as smoothies and parfaits. Red Mango kiosks, co-branded stores and self-serve locations can be found at sporting arenas, airports, tourist destinations and college towns. Red Mango operates more than 70 shops in 20 states.
