The jokes for The Blue Ball pretty much write themselves. Particularly when you consider they have both Stones and Blue Ball Bitter on tap. Yeah.
It's a decent enough pub. The food is about what you'd expect. The staff is friendly and the locals seem to be here all the time. It's clean, warm, and a good place to have a pint of "real ale", if that's your think. If craft beer, however, is your thing... you'll be disappointed.
