You can see a lot of New York City from the top of a double-decker bus. But, outside views of the Empire State Building and the Metropolitan Museum of Art are limiting. If you never venture inside these kinds of iconic places you’ll miss out on some pretty spectacular interiors. A new book encourages readers to look beyond buildings’ facades.  It’s called Interior Landmarks: Treasures of New York. On this week's Cityscape, we're talking with the book's authors, Judith Gura and Kate Wood.
