Book B is a bookstore and restaurant in the former Nam Fung Textile Factory in Hong Kong that sells independent books on design, art and the humanities alongside meals. The adjoining restaurant serves fried fermented tofu and curry, with coffee and cake available as well. The shelves carry no clear categories, holding 4D children's books, Hong Kong-made books, Japanese printed matter and oversized books as tall as a person. The number of books is small.
