Local bookstores have been hit or miss: for every Elder's Books that is well laid-out and has a lot of unique stuff, there's a Bookman/Bookwoman which is entirely disorganized, mired in its own political correctness, and apparently even unimpressed with itself.  For every awesome experience that's McKay's, there's a discourteous and ridiculous Rhino Books.
So I was concerned that Landmark might be extremely lame and lifeless, and at the first glance, it might be.  But their normal stacks are pretty decent, and their children's section is actually really nice.
But then they usher you into their back building, which has the appearance of an old old garage, but it's stacked with gobs and loads of books.  It was delightful!  In one of the old rooms, they have an area where you can get ten books for $20.  Nice.  I only chose one book, which was book of Norman Rockwell prints, but it was still only $5!
Absolutely, check this place out!
