This store is stocked to the ceiling and back again with all kinds of great used books. I've found great history selections, Washington DC themed stuff and very kitschy cookbooks. The fiction room is well stocked and is a good place to find older editions of a book that just had the movie come out (nice to avoid Jude Law peering at you while you read Cold Mountain). But the best bit is the mystery section where you can find things you didn't even know you were looking for. I've filled in older books in a series, found British editions with airport receipts still in them, and re-read the spy novels of my junior high days for decent prices. Just don't sneeze - the stacks are precarious but that is part of the charm.
