I have tumbled across this book before I left for my holiday. It is very useful: it fitted nicely into my small bag. I was impressed with the allergy information as this proven very useful when we had a take-away.
In spite of its size it has all the necessary information in English, pinyin (romanized Chinese) and Chinese characters as well. It covers the topics such as pronunciation, transport, direction, accommodation, shopping, banking, social aspects, food, health, etc. and comes with a handy English-Mandarin and Mandarin-English dictionary.
Overall I can say it is a very good value for money choice.
