When I went here, it was a great atmosphere. Very bustling and the staff were very friendly. The food was absolutely amazing... guinness stew was what my bf had, and he shared some of it with me, and I had bangers and mash. (I'm not even normally a fan of sausage, but authentic british food... hey...)
They do lose 1 star for slow service. It took forever to get our check when it was time for our group to go and when we did get it, they had screwed up a bit on it. That was the only thing wrong with the entire visit, though.
