Really the only thing I can say to recommend this place is that their potato soup is the best I've had in Charleston. It's also worth seeing the bands in the evenings, and a very social bar to hang out at. That said, anything other than the Irish food on the menu is terrible, the service is fairly slow, and the crowds make it difficult to carry on a conversation over your meal.
Pros: Good decor, good Irish soup, decent entertainment
Cons: Bad service, terrible non-Irish food, noisy
