Bangladesh
I decided to stop off in Dhaka for a couple of days on the way from Thanksgiving in Hong Kong to Bhutan. I stayed at the Six Seasons Hotel, which was very nice.
I booked a day tour (just for myself) from Taabu Tours that was very enjoyable. I especially liked the boatyard where ships are refurbished and old ships are broken up. This is very hard and dangerous work. One guy was removing rust from the side of a ship by banging it with a ball peen hammer. Imagine how long that takes. I got to talk to some of the workers and hangers-on. Fascinating! I'm not sure that the boatyard is on their standard tours, so be sure to ask. And there's no way you would be allowed to visit such a place in Western countries.
Also worth a stop was the brick factory. Make sure to check out the videos of workers carrying bricks on their heads (and wearing sandals). They are very strong.
