I have a habit of keeping visual notes of the best things, from what I've eaten to days I've spent. Bookstores in New York City are on the top of my best things list in life. Even if they're fewer than before--I still miss the old Rizzoli space, sigh!-- they're still numerous enough to keep me happy. I often just plan a weekend day with Brian around ending up in a bookstore. After sketching my favorite Manhattan bookstores, it took me a while and an illustration class project to get them all down.
My favorite of the favorites is probably Unnameable because it's the right mix of new and old, as well as in the perfect location for meandering around stores in Prospect Heights. Who doesn't want Ample Hills AND a book on a Saturday bike ride? A close second is Community Bookstore in Park Slope because it's cat is on the cover of a Japanese book about bookstore cats. I love a bookstore cat.
*update Feb 2017 Bookcourt closed! But soon enough Emma Straub is opening Books Are Wonderful in the 'hood.
