The Starbucks Reserve Bar on the 6th floor is open until 23:00. Bookstores and regular Starbucks are open until 23:30.
The assortment of books at the bookstore has more magazines about art and lifestyle than novels such as fashion magazines, movies, illustrations, and dishes.
Some books, such as Ukiyo-e books, cannot be found in ordinary bookstores, so it would be wise to use them separately with nearby Kyobunkan.

The underground depa basement is closed early at 20:30, but don't miss it because there are some side dishes that are about half price 5 minutes before closing.
