South city is a haven for doughnut lovers. Within a three-mile radius, one can pick from such long-john luminaries as World's Fair Doughnuts, O'Fashion Donuts and Donut Drive-In. While those mainstays are all dandy, there's a new kid in the neighborhood. Tucked away in the Southtown neighborhood, Eddie's is the most recent addition to the roster of south-city purveyors of doughy, fried treats. Eddie's doughnuts are firm without being too heavy they won't deflate at the touch or weigh you down after just one. The gleaming window case offers a cornucopia of glazed goodness, with enough old favorites and innovations (like a caramel long john or a custard-filled, delicately dusted with powdered sugar) to fill out a baker's dozen and then some.
