I was gonna recommend the Architecture Art Museum but that might be too polar for your tastes. I've always liked the drive to Red Wing. You should be able to find some good hiking trails to walk and shopping in town. You can enjoy a book hanging by the River or Lake Pepin. For food I will always recommend the Iconic Food of the area for the true experience. That Would be White Castles. Seriously tho, If you are in Minneapolis... you must have the Juicy Lucy at Matt's Bar. You should also try the Mason Jar in Eagan. They have a hotdish menu for the true Minnesota experience.
