I decorated my home office with an Irish motif, so I went to a store in Phoenix that was closing and bought a bunch of stuff at like 1/2 off. The owners were relocating to the Irish Cultural Center to run the gift shop there, so I learned a lot about the place and it DOES sound like a lot of fun -- I'll definitely have to check it out then!
If a parent or a grandparent was born there, you can do the paperwork (takes about a year). Google the Irish embassy or consulate for more info.
I know that shop, that's Pat Crossan's, he is a good guy and a great singer.
