Westsider Rare and Used Books is a great off-the-beaten-track shop where you can check out books ranging from Oscar Wilde to Malcolm Gladwell (two of my favorites), to “rare and used books” in other languages. The treat is really in the atmosphere, where you have to ask the bookkeeper to direct you to whatever you’re specifically looking for (he knows the exact location of everything) . . . although you could wander and browse for hours, easily.
