A word of advice, do not ask for the drink "Car Bomb" in any pubs. You'll be kicked out.
Ireland is pretty (except for Dublin), and a nice place too. I recommend all travelers going there to visit at least Glendalough's national park, the Cliffs of Moher, those thousands of years old grave mounds/tombs on the northeastern part of the country, and of course the Giant's Footsteps.
Have fun, it is a beautiful country, and now you can enjoy a pint without being inundated with smoke.
