It's a pub, but it's faux-Irish. They had English vinegar on the tables, Jameson sitting next to Bushmills, and turned off the rugby game to watch a hockey interview show.
The fish and chips had half the fish being awful chewy, the beef stew was authentic enough to be incredibly bland, and the darker beers we ordered tasted awful watery.
If you want strip-mall-irish, it might be the best Pittsburgh has to offer; we're thin on chains around here. Fado does it better, if you've been to one of those.
Try Mullaney's in the Strip if you want more authentic Irish. Hell, go down to Piper's British Pub and try the boxty.
