Pratunam / Siam
Pratunam Market (Thai: ประตูน้ำ) is one of Bangkok's major markets, focusing on clothes which makes it Thailand's largest clothing market. Pratunam market covers the whole area around and behind Amari Watergate and Indra Regent hotels with the rainbow colored Baiyoke I hotel and the towering Baiyoke Tower II hotels inside it. If you're a tourist do not hesitate to enter the small alleyways and jampacked small streets, the area is very safe unless you do something stupid like keep your wallet in your back pocket.
