Have guests from oversea, who want to have a dinner at Chao Phraya river, preferably Thai Food and in the old town (Rattanakosin) area. For me it's been some time; I have been a couple of times at Supatra Riverhouse, but that is gone...
What would you recommend (views and food quality)? Savoey, Sala Rattanakosin, The Deck by Arun, Above Riva, Rongros or any other one?

thanks!
