The notable thing about "Irish" bars, I think, is that there are so many of them in non-Irish places, compared to other types of "nation-branded drinking establishment."
This sounds terrifying I don't want a dart to fall on my head!
Some of them have the first and last (Beer Market near Christchurch comes to mind), but none have quite managed the shuffleboard.
I was in Ireland for the college football game at Avia last September and my hoppy beer loving friends took up residence there for the couple of days that we were in Dublin. Great place.
Another thing I've seen in a number of Wisconsin taverns and dive bars: small beer glasses that hold ~10oz (300ml) max that they give you with your bottle of beer.
