That magical experience awaits you at Mullen’s Dairy Bar in Watertown, Wisconsin.
This family-owned treasure has been crafting impossibly creamy, small-batch ice cream since 1932, making it the last surviving dairy operation in a city that once boasted 14 different dairies.
What started as Frank Mullen Sr.’s humble milk delivery route has evolved into one of Wisconsin’s most beloved ice cream destinations.
Today, the third generation of owners continues the tradition of making everything from scratch, right in the back of their charming Main Street location. You’ll discover a nostalgic atmosphere that feels frozen in time, paired with innovative flavors that keep customers driving hours just for a single scoop.
Ice Cream Excellence & Must-Try Flavors
Signature Creations: The ice cream here isn’t just dessert – it’s an experience crafted with 12% butterfat that creates an incredibly rich, velvety texture. You’ll taste the difference immediately in classics like their smooth vanilla and decadent chocolate, but the real adventure begins with their rotating selection of up to 25 unique flavors.
