Having seen a few past posts looking for information on Ireland, I came across John & Sally McKenna's website today. Their Bridgestone Guides were my eating Bible when I lived there for 3 years. He was (maybe still is) the food editor of the Irish Times. The newsletter is very chowhoundish.
My best advice to anyone traveling to Ireland is to buy either the Ireland or Dublin Guide when you arrive unless you have clued-in locals to advise.
I ended up moving to West Cork after reading his raves about the deliciousness hotspot that is centered in Schull. With many fine restaurants (in season) and cozy pubs, 3 award-winning cheesemakers, amazing produce, and stunning natural beauty, it is my favorite place on earth.
I have specific recommendations, hopefully not too outdated, if anyone is interested. If you're going to Ireland, it is worth a long detour.
