I grew up in Frederick, and moved in my 20s to Baltimore. As a 'beer snob', I would say their beer is alright, nothing fancy. However, the fact that they make their own, and don't charge a stupid ass cover in the middle of the country (or maybe they started, like every other bar in the 0.5 mile area...), I definitely give them a good amount of respect. I would prefer to drink there over any other place in Frederick. Of course, I am speaking of their beer, and not their food. That is another story completely!
Have you tried Barley and Hops? I don't think I've enjoyed a single one of their beers. Not like I go back to Frederick much anymore, though... it's been a while.
