The popular restaurant and bar closed on Dec. 26, 2012, after a grease fire ripped through it.
The new Hibernian has a two-story layout and rooftop bar.
Hibernian will be open 11 a.m. to 2 a.m. Saturday as they team up with Napper Tandy's to host a St. Baldrick's Shave-a-Thon and block party on Glenwood Avenue. That event starts at 1 p.m.
The pub will be easing back into its normal hours. Tuesday through Thursday it will be open 4 p.m. to 2 a.m. serving a limited dinner and late night menu. On Friday, the restaurant is planning to resume its regular menu and hours 11 a.m. to 2 a.m.
