Book Cafe Twentieth Century is a book cafe on the second floor of a bookstore building in Kanda Jinbocho, a two-minute walk from Jinbocho Station. It serves curry, cake, and coffee, with beef curry and mug-sized drip coffee made from freshly ground beans as its main items. Visitors can take out some old books to look at, and the space also holds exhibits and Ultraman figures. On days when events are held, a quiet reading space is not available.
