If you mean the night market: yes it is different from Chatchai market. Chatchai market is a covered market (vegetables, fish, meat and clothes) that opens really early morning (even at 2 AM), certainly for the food part of it. it stops early afternoon (however some cloth shops stay open till early evening. it is squeezed between Petchkasem road and Dechanuchit road near Soi 72. The night market (open air) opens only at night time (about 18h00) and consists of souvenir shops, T-shirt shops, wood carvings and delicious sea food stands (especially lobster). It is in soi 72 of petchkasem road.
