Potato doughnuts are a must-try at TriBecca's Sandwich Shop

Last week, the Chicago Tribune's Nick Kindelsperger declared the Cuban sandwiches at TriBecca's Sandwich Shop "jaw-droppingly gorgeous," so naturally I zipped over to the Avondale shop for a try.

• Their Cuban ($12.95) delivered a fine, hefty Midwest take on the porky, pickly pressed sandwich, but what really caught my eye was the "loaded baked potato-nut" ($4.95).

What is it? A savory doughnut using Illinois potatoes in dough fried in clarified butter. The fluffy fritter is then topped with sour cream, bacon, chives and cotija cheese.
