The lowest rating is 0 and the highest is 6. 1 - A notch better than a zero. Low on decor, style, comfort and cleanliness and the beer selection is wanting, but at least you won't catch a disease from the glass and you'll probably feel reasonably safe. Edible if not interesting food, more than a couple of beers on tap including a local micro or two. You can feel comfortable here.
Food is good, the place is comfortable, the decor even looks like someone thought about it.
5 - A really good pub. Decor is very comfortable and you'll definitely be back here regularly. 6 - Wow. This place is so good you've changed your address and moved into the comfy chair in the corner. The beer selection is impeccable and the food is a dream.
