24hrs (closed Sat 10pm–Mon 4am)Average doughnut: $1
Expertly made doughnuts, available 24 hours a day. Is there any doubt why this South Side shop has become an institution? It's hard to go wrong with any doughnut here, but if you have trouble deciding, go for the buttermilk flavor—these lightly glazed, slightly tangy cake doughnuts achieve what very few of their kind can: an airiness resembling that of their yeast-risen brethren.
