Bangkok is a city of contrasts. Here and slums, and ultra-modern roads, and huge office buildings. Perhaps it can be called the heart of Asia. It is huge and varied. Any person will find a place where he will be insanely good.
You can walk around Bangkok for more than one week and find something new and interesting. In order not to get lost in the city and not to miss an interesting place, you can take a map from the first INFO kiosk that comes across.
