Hey... I do stop by there sometimes. I don't buy too much manga because the vast majority of what they have is Japanese-language, but I like to browse the latest Dengeki, Newtype, etc. - + all the various art books and such.
I also enjoy the Kinokuniya in San Jose. It's adjacent to the very cool Mitsuwa Marketplace, which includes IMO the current best ramen in the Bay Area, the #9 at Santouka.
