O'so Madhouse is a diamond-in-the-rough tap house serving amazing stouts, porters, and sours. The knowledgeable staff recommends their Imperial Cookie Oatmeal Stout and other high-quality beers. The tap house covers a wide range of beers, from bourbon barrel stouts to pineapple upside down sours. The cool space, located near East Washington Ave, offers free underground parking and a great bar manager.
