One Award-Winning Ice Cream Parlor Worth Tasting Has Been Serving Oak Park Since 1919

Hans Petersen’s wartime ingenuity created what would become Oak Park’s sweetest legacy.

When butterfat rationing threatened his Chicago ice cream operation during World War I, this Danish confectioner made a brilliant move:

He relocated to Oak Park where he could secure the premium ingredients his recipe demanded.

Over a century later, that same recipe still churns in the heart of Oak Park’s Frank Lloyd Wright historic district.

Petersen’s Ice Cream Shop sits as an Oak Park institution at the top of every visitor’s “must-do” list, serving up award-winning scoops that have earned nine blue ribbons from the Illinois State Fair.
