When it comes to soft-serve ice cream, this nationwide chain is the "queen." The Dairy Queen. You'll find sundaes, banana splits and the infamous chocolate-dipped cones as well as fast-food burgers, hot dogs and chicken sandwiches. We think it doesn't get much better than an Oreo Blizzard on a summer day. And it isn't a party without one of DQ's Chillabration Cakes.
