Pubs (Irish preferred) in Columbia?
Are you looking for dinner, or just to drink?
I've been to Kelsey's off Rt. 40 a couple times. It's a respectable Reuben, and they have Harps on tap, which I love. I wouldn't consider it chow worthy though.
I'm really wondering if there's an Irish pub in the whole area that's actually good. The category seems to be synonymous with mediocre food and cigarette smoke.
