I'm Irish in NYC, I've been here for almost 10 years, and I don't have one Irish friend. I think the reason a lot of Irish people have mostly Irish friends is because they move here with people from home and cling to them because they don't like feeling alone. I moved here by myself not knowing anyone which really forced me to put myself out there with the folks around me who where mostly American. I was also a bit of a loner back home (partly why I moved here) so was very comfortable with my own company. I've said this before, but Retro is really missing out on the real NY experience by not immersing herself in the culture and the people. She may as well just live in Ireland.
