Wow this is a gem. Attention to detail and a joy for all your senses. Beautiful artifacts tell a story and all surrounded by orchids in stunning shapes and colours. The thai restaurant gave us the best meal. All the beautiful thai flavours and textures on a plate. I would say it is a must to visit even if you dont stay in The Siam. Not fancy just authentic and so good. And the trip on the Chao Praya river to get there is such a reliefe from the Bangkok traffic. Amazing sunsetview so bring your camera.
