If you're looking for soft, moist, doughy, fried glazed doughnuts then I'd recommend Brooklyn Baking in Waterbury. They don't do a ton of flavors, they're not trendy hipster doughnuts with a pile of candy or cereal or bacon or rainbow frosting (or all of the above) on top, but they're simple and delicious. I've never had a dry doughnut there.
