Revelers in green flooded area bars all weekend long to celebrate the patron saint of Ireland, and O’Donovan’s (2100 W. Irving Park) was no exception. On Sunday, the Northwest Side bar chartered a bus down to the South Side Irish Parade, embarking at 10:30 a.m. and dropping off parade-goers back at the bar at 5 p.m.—for even more drinking and celebrating. We caught up with some folks who kept the party going post-parade.
