On the grounds of Snug Harbor in Staten Island lies a cultural gem - community art classes and community galleries/shows at the ArtLab. Drawing, Photography, Printmaking, and more for both kids and adults. I took a Basic Drawing Class and the instructors were all locally based but all professional artists. These are no amateur classes! And cheaper than anything you would get in Manhattan. Although I don't have firsthand experience, I have heard their kids art camp is fabulous.
