For coffee table worthy tomes to hard to find titles, the selection is broad enough to be interesting but well curated - no filler here. For design travelers, they carry the full line of the (excellent!) Wallpaper City Guides.
Located on the 3rd floor of Luminaire (301 West Superior) - be sure to check it out next time you are in the neighborhood. (And if you are there before July 31, 2010, you can also see the Naoto Fukasawa exhibit).
