If Mason City Can Create Entertainment Center, So Can Rochester Get our free mobile app It looks like Mason City, Iowa, is turning their downtown mall into an entertainment center...someplace for the entire family to have fun. Does this mean it might be possible to do the same thing with Shopko South in Rochester, Minnesota? First, the most recent update...the guy that is going to build a hotel just bought the Southbridge Mall in Downtown Mason City... Sure, they're starting small, but the plan is the kind of thing people in SE Minnesota have been saying Rochester should have for decades now.
