I think people appreciate it as an icon but many folks born here (which I was not) avoid doing touristy-seeming things even if they’re interesting. I was working in an office near dowtown on 9-11-01, and in the weeks afterwards I informally polled my colleagues to see how many had actually gone up to the top of the World Trade Center. Almost everyone who grew up outside of the city had done it (many as kids), but very few of those who grew up in the city.
Why do you need to be talked into liking NYC? If you like urban living, it’s urban living concentrate. If you don’t, there’s no convincing you to spend more than a day or two a year there. I read somewhere recently (I forget the context) that the English people are proud of London and the French proud of Paris, but Americans in general are not proud of New York. I guess there a lot of reasons why that is, but it’s our world city, folks.
Anyway, I like these, which aren’t that touristy: the Greenway bike path down the Hudson from Inwood to the Battery (if you don’t mind the risk, biking is a great way to get a different view of things); a million choices for cheap ethnic food in Jackson Heights and Flushing, Queens; the Cyclone (the scariest roller coaster in the world because it’s so freakin’ old) and the Wonder Wheel and all of Coney Island (plus the Russian food in Brighton Beach) (and the bike path down Ocean Parkway for that matter); Central Park north of the reservoir; water taxis (I take them for no reason) and the (free) Staten Island ferry; a thousand free outdoor concerts all summer long; the fact that at these free concerts the city will easily churn up a few hundred or a few thousand fans of Algerian rai or Senegalese pop music or free jazz or someone like Jimmie Dale Gilmore; bluegrass at the Baggott Inn on Wednesday nights; the Russian baths; the fact that if you decide you want Tibetan or Peruvian or West African food you can look into Zagat’s and there is a choice of restaurants; the Sunshine, Film Forum, Angelika, and all the other little cinemas; the salsa and merengue blasting up my air shaft on summer nights (really); the quiet side streets of Harlem early in the morning; the Babel you hear on the streets every minute of every day; the fact that you could pick a block at random that you think you’re familiar with and there will always be something you hadn’t noticed before or something that had changed since you’d been there last.
My top touristy things would be the Museum of Natural History (I go once or twice every year), Shea Stadium (named for the famed guerilla leader, Che Stadium), the 3-hour Circle Line trip all the way around, Central Park, the Empire State Building at dusk, a walk across the Brooklyn Bridge, Chinatown and Little Italy at night.
For off-brand museums, there’s The American Folk Art Museum. The Museum of Sex (233 Fifth Avenue) is not great (in my opinion – I’ve only been there once), but it is different than MOMA, I’ll grant it that.
I could do the negatives too, if you’d like.
