Hi All! I live in New York, and I'm taking notes about all these great recommendations!
I actually wrote the guide, "Markets of New York City." (Thank you, Toy Story!!!) So I got a Google Alert, and I thought I'd pop into this awesome discussion.
The guide includes over 40 of the city's best artisan, farmer, food and flea markets! Some amazing new markets have opened since the guidebook came out too. If you are coming to town, I'd love to give you recommendations based on what you're interested in. And you're welcome to hang out with me at the markets - I'm out exploring almost every weekend.
For foodies coming in the spring, I'd definitely recommend the Brooklyn Flea. Some of the most innovative foods in the city are coming out of this market, so go hungry! Of course Chelsea Market is fantastic, and the Grand Central Market has some great food shops for picnics and foodie souvenirs. Up in the Bronx, the Arthur Avenue Retail Market has KILLER Italian food - try the eggplant parm at Mike's Deli. Or the Moore Street Market in Brooklyn for Caribbean cuisine. And don't forget the farmers markets all over town. They sell mostly fresh produce and not a lot of prepared foods, but it's lovely to visit a new neighborhood by checking out their local farmers market. I discover new and amazing things every time I go to a market.

And now I'm hungry.
Don't even get me started about the artisan and flea markets. So many treasures to be found.
