This is a fluffy little guide to Siem Reap. The design and photos are nice, and it is compact enough to bring with -- if it were worthwhile.
It's posed as an insider's guide to the high-end near the magnificent Angkor complexes, but it lacks some useful tips, like hiring a guide (and that your guide and tuk-tuk driver will be getting kickbacks from the shops and restaurants you are dropped off at).
