I've bought Tony Buzan books from here before. There is a wide range of books you can buy, from cooking to fiction to hobbies books. The isles are easy to navigate and there are enough staff to help out if need be.

Not enough staff, but a good selection of sci-fi and fantasy. The store is quite hard to get around with a pram, with crazily enough the children's book section being the most inaccessable for prams!

Approximate cost: $30
