We take a trip to the Windy City to check out the coolest doughnuts around. One hotspot specializes in huge, super fluffy doughnuts that are so good, they sell out fast. Then there's a full service restaurant that has doughnut and coffee service every morning and has invented a unique and delicious hybrid called the "doughscuit." And you won't want to miss the locale where mini doughnuts are fried fresh all day and can be topped however you want -- or even crumbled into a milkshake!
