Petersen's is a welcome addition to the abundance of froyo and gelato options in Old Town. Originally from outside of Chicago, this is some good quality ice cream. My favorite is the Mackinac fudge in one of their huge dipped waffle cones. Yummm.
The guys who run it are super friendly. Hi Terry! And make sure to say hi to Petey - the cutest little 3 lb ball of fluff you'll ever meet.
