Politics and Prose, DC's quintessential bookstore, has an excellent children's room, weekly story hour, and great kids' author readings and book signings.
Shop local! Politics and Prose is the most amazing, smart-staffed, and energizing bookstore we've ever been in. The selection is superb, and the helpful, always available staff are true experts. The Children's section is downstairs and is run by the former owner of the Cheshire Cat Bookstore (a late, great D.C. institution). For anyone who's ever watched "You've Got Mail" with Meg Ryan and Tom Hanks, Politics and Prose is very much like the bookstore Meg Ryan's character ran in the film. Be sure to check out their events page before you go - EVERY author touring D.C. speaks here and almost nowhere else.
