12. Mo's Irish Pub

City: Milwaukee, Wis.
Address: 142 W. Wisconsin Ave.
Website: mosirishpub.com

In the heart of downtown Milwaukee sits Mo's. Though it has all the trappings of your standard Irish pub, Mo's stands out for its serious St. Patrick's Day celebration. How serious? They open at 6 o'clock in the morning. That serious. For the first two hours the pub will be open on Saturday, a free bar tab will be raffled off every 20 minutes. Early bird drinks the worm. And goes on to ravage whatever else the day brings.
