+1 for the Folkhouse. They always have the 8 Degrees brews and Dungarvan as well as Stonewell. They also have Sierra Nevada, and Rogue. I know, not Irish but variety is nice nonetheless.
Every time I've been to the Bulman they've had Rebel Red and I believe they have Stonewell and Dungarvan.
The Blue Haven also carries Stonewell, can't remember if they have any others.
