This popular indoor/outdoor market is open every Sunday year-round, from 10am to 5:45pm (and Saturdays from mid-November until Christmas), and features great vintage and antique merchandise plus handmade items and gourmet food—much like a European open-air market. Look for fashions and jewelry of all descriptions; vintage and antique home furnishings; books, CDs, DVDs, prints and eyewear. GreenFlea is very family-friendly—with something for everyone—and located in a great Upper West Side neighborhood. (Proceeds benefit NYC public schools.) Established in 1985, expect to see 250 vendors on average every week.
