MBF is a great firm. They're very strong in IP and litigation. All the major firms in Milwaukee (Reinhart, Quarles, Godfrey, MBF) except for Foley are very good regional lawfirms. Foley is the only truly national firm in Milwaukee. If you want to work 2200 hours and do Fortune 500 work on a consistent basis, go work at Foley. If you want high level, quality work where you're not spending every living moment at the office, any of the other firms are great.
