Buy your favorite local crafts aboard a boat at the Damnoen Market. Eat pad thai, get a native bag or just simply ogle at the albino snake at the bank. Make sure to have your local currency ready to get the best rates from the merchants.
Bangkok is full of awesome attractions. Cultural values of the nation are super amazing. The rich culture has its roots in all the aspects of life here. This market is one of the places where you can have the best interaction with the people who give great vibes of their awesome cultural values. I would love to visit this place.
