A summertime hot spot, this seasonal Oak Forest favorite serves up a wide variety of ice cream, shakes and popsicles to help you beat the hot Chicago heat. The patio seating area provides you a place to enjoy your ice cream before the elements turn into soup. A favorite summer activity, the crowd at Jack Frost can range from families to baseball teams to two people enjoying a first date. One thing is for sure, it's not officially summer until you have had some Jack Frost ice cream.
