I just returned from a week in Dublin and I found NOTHING. The Peterson store on Grafton street had more cigars and EDC items than pipe stuff. There is a cool little tobacco/Cigar shop next to The Temple Bar, but a 50 G plug of Yachtsman was 25 Euros. The tobacco tax is so high there that it really isn't equitable to buy tobacco.
In the three countries I visited (Ireland, France, Czech Rep), I saw a lot of Vaping, vaping advertising etc...
Dublin is a great city to visit. The fellas on this site gave me some great suggestions in another thread. One of my favorite things I did was a day trip to Howth... 4 Euros, 20 minutes on a train. Check out Howth. Great seafood restaurants, scenic, great folks. I even met a former Professional Football player/coach.
The Guinness is still great.
I went to the Pearse and Lyons Whisky Distillery. It was amazing.
