18. The Plough and the Stars

City: San Francisco

The live music draws a mixed crowd of young and old enthusiasts of all things Irish at this worn-in, old-world pub. When the traditional music stops, come back to America by playing Steve Earle on the jukebox while you smack the pool balls around. SF Weekly named it the "Best Irish Pub" in the city; if you've had a Guinness here, you didn't need that particular alt-weekly to tell you that.
