Owner and chief bartender Curt started collecting single malts over 20 years ago. He merely says he has one of the best single malt collections in the upper midwest. Once when I was visiting, I met a man who travels the world sampling single malts (750 and counting) and he stated there is only one other bar in the world that compares to the Union House.
The food, wine and staff are excellent too, and Curt draws customers all the way from Chicago an hour and a half away. The crisp-skinned roast duck is the best I've ever had.
