Green Apple's victory in this category is, well, hardly a stunning upset. After all, if our readers' poll is anything to go on (and we hope it is) it's San Franciscans' favorite used bookstore year in and year out. And the pleasures of Green Apple are many -- its well-organized stock is tucked into so many odd nooks, accessible by several pleasantly creaky staircases, that any normal person can easily spend a whole afternoon browsing unexpected title after unexpected title, inhaling the faintly sugary smell of old book paper, and absorbing all manner of surprising and delightful new facts and information. Besides used books, Green Apple sells many of the best new titles (often with handwritten recommendations from the staff -- always the sign of a quality bookstore) and offers some serious bargains on remaindered stock.
