The food is acceptable. however, it's VERY expensive. I found no motivation to go there the second time since there are many better Thai restaurants in town. Chaophraya Thai restaurant is much better. The food and service there are great and it's also ranked the 5th best restaurant in the Manchester. Also, Phetpailin and Try Thai in China Town are also a lot better with affordable prices. Furthermore, the manager of Koh Samui is very rude and mannerless (the dark and bald guy) , i went to tell him that it was very cold at my table. He ignored me and pretended that he didn't hear me.
