From Apple Pie to Zeppole: Chicago Dessert Options Satisfy Day and Night
"Bar Siena's walk-up dessert window, BomboBar, offers a riff on doughnuts - the "bomboloni" - an Italian hole-less doughnut Top Chef alum Fabio Viviani serves at his restaurants, Siena Tavern and Bar Siena. It's the specialty of the house at BomboBar and works wonderfully in the West Loop for dessert or post-party hunger pangs. Order one, four, six or a dozen and any of six rotating custard flavors that you inject into the doughnut."
