Bangkok's largest Chatuchak market, which is only open on Saturdays and Sundays.
I thought I should go there, but I didn't have time on weekends, so I went to a shopping mall right next to the market. This is an air-conditioned shopping mall with a market atmosphere.
It is a fun place with various stores, souvenir stores, fashion stores, recycle stores, and maniac stores such as figurines. There was also a well-stocked food court.
