There is the tourist Chinatown in Bangkok, and the Chinatown where people actually live and work. Machine parts seem to be an especially big thing, making parts of the place look like a huge junkyard. But there are 200-year old mansions too.
Downtown, the Saffron Sky Garden bar, built into a big cutout of the Tai Wah skyscraper is a nice place to conclude the day, and this trip. Bangkok is a curious mixture of ultra-modern and deeply traditional.
