I will recommend Aran wool things. Authentic Aran sweaters, hand-knitted from local Irish wool, offer exceptional durability and longevity. My friend used to give me one sweater made of Aran wool, and unlike modern sweaters, they can be worn longer.

I second the idea of an Irish wool sweater. There are shops everywhere, you can't go wrong.. My wife bought one in Galway (near the Aran Islands). Or, there are excellent wool socks to be had.

Regarding beer, you really need to try a stout, like the ubiquitous Guinness. It's very unlike the Bud-Coors-Miller stuff in the U.S. You can ask for "a half pint of the black stuff". There are nowadays a number of craft breweries, and many will make a good IPA. I'd try that also, as it's also unlike the Bud-Coors-Miller lager beers.

On restaurant menues you may see an Irish stew with Guinness in it. Don't worry, it will not taste like beer. It will be delicious. And great seafood is everywhere, including fish & chips. Portion sizes are usually pretty generous.

For a souvenir: In Belfast, I bought a nice illustrated book at the Titanic Museum.
Or you can buy a t-shirt in Belfast with a picture of the Titanic, and the caption:

"It was ok when it left here"

Re: beer, in Cork, try Murphy's or, my preference, Beamish.
A wool hat can be useful during the trip and makes an easy-to-transport souvenir that you might use more at home than a sweater. Those sweaters are too warm for where I live.

I have tried beer world over and have yet to really like one, but will definitely give it a try in Ireland. The closest one which I tolerated was a small glass of pale lager in Prague on a hot day, and that is way different than Guinness. Much prefer wines and some cocktails. May be suggest some good ones based on Irish Whiskey.

Aran wool-based items were on our list. Regarding Jameson Whiskey, I heard that it may be cheaper to get it in Costco!

I heard seafood is good especially in Cork and Galway, so would love to get some recommendations about good everyday places to eat them, street food to market to mid-range.

Semiretired, sounds like Guinness wouldn't be your favorite, but it's Ireland, you are required by law to buy at least 8 ounces of the black stuff.... (?)

But any pub will have some lagers to try. If the alcohol is off-putting, there are some good alcohol-free beers. I think any pub would have something bottled you could try. Many big names, including Guinness, have alcohol-free choices now, and they taste good to me.

I'm not a big beer drinker, and I never had stout at all until my 5th trip to Ireland. My Irish beer of choice has always been Smithwick's. I was surprised by how much I enjoyed the Beamish, though.
Goldie's in Cork is above mid-range but worth checking out. Reservations required. It's a gill-to-tail seafood restaurant. The Farmgate Cafe in the English Market serves nice food, and the setting is lovely! I had a nice glass of dry cider with my lunch there.

If you're going to Galway I'd definitely recommend a tour to the Aran Islands. I can't recommend a company, because I did it on a Rick Steves tour, but I really enjoyed the outing. And it is where I bought my Aran sweater. Seemed appropriate!
