My mother-in-law just introduced me to a pretty cool thing on the UES & UWS - Scribble Press. Kids can write and illustrate their own books and then have them professionally bound on site. With a wall of markers, pens and inspiration, kids can set their creative minds free on the pages, whether it be a 8 page board book or a longer "chapter" book they have in mind. I definitely made may share of books as a kid (though they were decidedly less "professional" -- we bound them ourselves with cardboard, contact paper, glue and string). This will definately be a holiday go-to for a fun afternoon. They also do classes and parties. www.scribblepress.com.
