Occasional Gaelic Football games at the Rugby Club, where there was also conspicuous Irish support during the Six Nations. There's an Irish Society somewhere (try Marhaba magazine?) who have their major shindigs at Garveys. Try whistling The Soldier's Song at Carrefour and see who comes running.
A priest once told me I had Irish ancestry, but of the iniquitous planted land-owning sort, so I guess that's me out. Anyway, I prefer Kilkenny.
