While I don't go out of my way for Harp on its own, it is the sine qua non companion to Guinness in a true Black and Tan. And for that, I would walk to the ends of the earth.
really what's better than an Irish whisky in a green jug? It could only be more irish if it was delivered by a leprachaun.
You have your pint glasses so now you can properly serve an honest-to-goodness Irish stout. The Guinness family has been brewing Ireland's most popular beer since the 1700's. That's a pretty good track record.
