One thing that is tough about pubs is that it takes a little age before they feel authentic. O'Shaughnessy's hasn't been open in the Arena District for too long, but enough to show they have staying power. The place can get overly crowded before or after Arena events. My friends swear by their fish sandwich. Drinks aren't a great deal, but if you are looking for an irish pub in the arena district, this is pretty much your only choice.
