Now in its 22nd season, O'Malley's of Weston presents the biggest little festival in the Midwest with three stages and over a dozen great Irish music acts in O'Malley's Pub, Lagering Cellar, and Courtyard, with an exceptional line-up of national and international headliners and regional favorites. About 10,000 people attend this festival celebrating all things Irish - music, dance, crafts and wares, and (of course) food, beer, and whiskey.
