Being a New Englander, Aidan, I am of the opinion that NYC is the most overrated city in the world, with grossly inflated pretensions of sophistication but hopelessly provincial.* And now that I've %!$$ed off everyone in that fair burg, I will add that many, many people love the place, and I would not be the one to say they're wrong. In fact, I've always had a good time when I've spent time there, and there is certainly something for everyone...but it's a mighty big haystack.
Let us know what you think of the dime-a-dozen Irish pubs!
*I will further add that New Yorkers likely would say the same about Boston, and I won't argue. Indeed, one might say the same about American culture in general. And now I'd better shut up before I start a war.
