Tourists come to Bangkok for many reasons: a night of love, a stay in a luxury hotel, or simply to disappear for a while. Lawrence Osborne comes for the cheap dentistry, and then stays when he finds he can live off just a few dollars a day.Osborne''s Bangkok is a vibrant, instinctual city full of contradictions. He wanders the streets, dining on insects, trawling through forgotten neighbourhoods, decayed temples and sleazy bars.Far more than a travel book, Bangkok Days explores both the little-known, extraordinary city and the lives of a handful of doomed ex-patriates living there, ''as vivid a set of liars and losers as was ever invented by Graham Greene'' (New York Times).
