Went here for St Paddy's 2011 with a group of seven people and we weren't that impressed. The line took 4 hours to get into the "most authentic Irish pub in Toronto", according to BlogTO. When we got in it wasn't that great. We all looked at each other and said " We waited 4 hours to get in here?".
There was a special St Paddy's day menu which was hand written, photocopied and carried no prices. They carry a full bar. We ordered Guinness, Magners and Irish car bombs. The car bombs were made incorrectly.
They do have some decor covering the Easter uprising which led to Ireland becoming a Republic but this doesn't make it an Authentic Irish pub. I wouldn't go out of my way to go back.
