Bookstore in the movie

Rizzoli's is an honest to goodness actual bookstore in New York. They are located at 31 West 57th Street between Fifth and Sixth Avenues. I thought they had gone out of business but they appear to have a website: http://www.rizzoliusa.com. (I am not an employee or owner of Rizzoli's, but I have fond memories of shopping there several times.)
