You've heard about the reading room at the New York Public Library, haven't you? Then I need not go on. Just look at it. And you're allowed to hang around in there!
This marketplace is home to tons of amazing local restaurants, shops, and vendors— from flowers, meat and cheese, wine, and a food court downstairs. There is definitely something for you here.
One of my all time favorite shops. They have amazing succulents at reasonable prices. It's always a pleasure to stop in and see what they've got that day. Ched, the owner, is not only extremely knowledgeable but totally hilarious. Every plant has been personalized and anthropomorphized.
