I ate at the buffet in mid January. It is on the 7th floor poolside. I don't know if it is still available as I am away, this buffet is 300 baht, all inclusive and believe me, it is fantastic. Extremely high class with many options, from sushi, seafood , salads, desserts to blow the mind, great service. It is definitely not to be missed! I will be back in Bkk on Thursday and will check it out. It is located on soi, 2, a short walk from nana entertainment complex.
