Fodor's Expert Review John Sandoe (Books) Ltd.
This atmospheric warren that crams some 25,000 titles into an 18th-century building off King's Road is the antithesis of a soulless chain bookstore, so it's no surprise it has attracted equally idiosyncratic customers like Tom Stoppard and Keith Richards. Staff members are wonderfully knowledgeable (don't try to figure out how the stock is organized without their help), and there are a lot of them per customer—if a book isn't in stock, they will try to find it for you, even if it is out of print.
