We didn't get to see as much of Ireland as we would of liked. But what we did see was great. The Wicklow Mountains (a few films made there) were great and beautiful. Also the town of Killkenny was great too. Ran into some former Ontarians in a pub there too, really is a small world.
If you want a great burger in Dublin go to BoBo's on Dame St, you won't regret it. Belfast was fantastic too, titanic museum, Giant's Causeway, you can't go wrong.
