Rodney Zimmerman, co-owner of Ally's Bistro in Menomonee Falls, had heard about Mandel Group Inc.'s plans to redevelop a historic powerhouse building in Wauwatosa. Known as the "M10" building, it would be redeveloped for commercial uses as part of the Milwaukee-based developer's mixed-use project that also includes a 102-unit apartment complex and 119-room hotel. The project is at 10460 Innovation Drive in Wauwatosa. Zimmerman thought it was the perfect location to expand the business. "For years, Michelle (Zimmerman, co-owner) and I talked about having a second location, and if we were to put a thumb tack on a map, it would've been just about exactly where this is," Zimmerman said during a recent tour of the M10 construction site.
