Previous reviews regarding this experience are pretty much on the money. I doubt that you can get a better dinner cruise in Bangkok unless you go for a full private boat.
Things started off fairly flakily in the attempt to book the trip, as there seemed to be some doubt as to whether or not space was available on the date we requested. The online booking system suggested not, but Tripadvisor said yes, so I tried contacting the hotel directly, but didn't get a reply until we were actually checking in.
At this point, we were confident of our place, and I then had a look at the menu, realising with only about two and a half hours before we were due to arrive at the dock that there was a lot of seafood included, so I rang down to the management to ask for a non-seafood option - and, bless them, they switched menu for me with that little notice.
At the appointed time we arrived at the departure lounge, received some very welcome cold (non-alcoholic) drinks, and waited to be led aboard.
Service was impeccable, attentive and precise. The food was a nicely-selected variety of flavours, beautifully presented in small courses but still enough that we were not going to leave hungry. We chose the Sakuna rosé, Anantara private-label wine to accompany the food, because - well, why wouldn't you?
I had signalled ahead that this was a birthday treat for my wife, and the waiting staff duly presented a beautifully-boxed small birthday cake at the end of the meal, with an accompanying round of "Happy Birthday to you".
Obviously the river views are a given - illuminated bridges, temples and the Royal Palace - plus the sight of many of the Big Buffet Boats hurtling past, lit up like Christmas trees and with dance music pumping out. This contrasted so vividly with the qualities of the Manohra, moving serenely in candle-light with quiet background music.
I don't think that I can add to anyone else's superlatives on this.
Is it more expensive than the other dinner cruises? Yes.
Is it worth the difference - oh, yes.
Only one jarring note which stopped me from giving the Full Five Points - if you have the tables nearest the bow, and, therefore, just behind the helmsman (we had Table 1), you get a constant noise of squeaky, staticky river-traffic radio chatter, audible over the background music. Might I respectfully suggest to the management that providing the helmsman with an earpiece would improve the ambience considerably?
