I have a real problem with Thom H's review. I have gone to "The Muck" many a time and to say they didn't know what you were talking about with regards to getting you a Guinness(proper spelling Thom) is ridiculous. They pretty much serve nothing but and it is a fine pour.
As for a review...it is a friendly place with great food, great owner named John and um...
anyway, it might not look appealing from the outside but it is truly nice inside.
