I cannot recommend this book highly enough. Anybody trying to learn Greek should snap it up immediately. The title acknowledges that the book is for beginners but when learning Greek you can feel like a beginner for a very long time! That said, if you have worked your way through an introduction to Greek Course such as the BBC Course [ASIN:0563519762 Greek Language and People Course Book]]or the Michel Thomas Greek courses [ASIN:0071742190 Speak Greek, Advanced: bilingual (Michel Thomas Method Speak...)] then this book will really help you drill down into the language. The book consists of twenty short chapters dealing with various aspects of Greek life usually containing a droll anecdote or two, notes and a vocabulary. I have read 14 of the chapters so far and they have all been good. The vocabulary is very extensive, the notes contain information on colloquial phrases (I find this very useful as such explanations are often missing from dictionaries) and the book is of a handy size. This is a big positive for me as it means I can carry it around on my daily business and have a little read when I have a few minutes spare time (e.g. on a bus or train or in a coffee break). If you have been learning Greek for some time, you will still find this a useful read but you probably won't need to dip into the vocabulary quite so much as other beginners.
I have not needed to use a dictionary very much to use this book but I have occasionally had to make further reference to a grammar book and a verb list. This is no bad thing as you cannot revise the basics of any language too many times. The book was written in 1964 and thus some of the material seems a little 'quaint'. This might make you smile but I do not think it detracts greatly from the value of the book. Indeed, some more nostalgic readers might enjoy this.
