Hg2 Buenos Aires was exactly what I was looking for. Of the three guides I took with me to the city, this one never left my side. Aimed at the more discerning traveller, the detail of some of the entries really impressed me. To the extent that I was able to choose a bar or club depending on what day of the week it was. It was surprisingly accurate as well.
Also of note, because of the chic design, taking the dust-cover off, you can carry this guide book with you and not look like an idiot tourist swamped with unsightly literature.
I really would recommend this guide to anyone, even backpackers. This city is so reasonably priced, that anyone can profit from the cities more glamorous destinations as suggested by Hg2.
My only concern is that Buenos Aires is notoriously difficult to navigate as it is so rigidly grid plan. Another guide book such as an Eyewitness guide is also necessary, even just for the use of its more detailled street plan.
Well done Charles, some excellent research. You must have had fun writing it.
