The Guardian's Books Blog proposes some first stops on a literary pub crawl, including a mention of the numerous watering holes to be found in the fantasy genre:

Okay, who slipped us all a vellocet in the Milk Bar? We seem to have turned the wrong corner ... and things have all gone a bit odd. Ah, we must be in fantasy land. You can say what you like about fantasy fiction, but those writers certainly know how to dream up a good pub. Take The Vulgar Unicorn, for example, the hub of the "shared world" anthology series created by Robert Asprin, who died earlier this year, and the setting of stories from the brightest lights of the science fiction and fantasy firmament. Speaking of which, you could have a fairly hefty pub crawl through the imaginary inns and taverns of JRR Tolkien's Middle Earth. One of the most popular in the Lord of the Rings trilogy is The Green Dragon at Bywater. It's a Hobbit pub, mind, so the biggest serving you'll get is a half a pint. I kid you not.

This short paragraph barely scratches the surface, of course.  Out of professional curiosity, what are your favorite fantasy public houses (besides the Accidental Bard, of course)?
