Gentle advice: choose the siu ma only from the a-la-carte and enjoy the panoramic view of Chaophyra river on this 36th floor, the top floor of Chatrium riverside. The other dim sum are not worth trying, not even mention their dim sum lunch buffet at THB695 net. The waitress asked for my comments on their food quality and insisted on why I said "average". I simply replied it's way below the Cantonese dim sum standard and in considering this price, it's not worth it. Interesting that she didn't say a word; so what an unnecessary question for an answer they don't wanna hear.
