Even before you enter, you can see Serendipity is not your average bookstore. Walking into this shop is a little like walking into the creative mind -- books on all subjects are piled to the ceiling, interspersed with the occasional piece of art or musical instrument. This is a bookstore for people who truly love books, and since it specializes in used and rare books, invest a few hours wandering through the stacks and you are sure to come away with some gems.
