I am surprised to see the low ratings given to this drama. I thoroughly enjoyed it and I think it is comparable to Yanxi Palace. The story kept me captivated with the many going-ons and mysteries behind the characters in the Forbidden City. There is sufficient suspense and twists throughout the drama although I must admit that it was difficult at times to understand the motivation behind each character.
I like the way the stories behind the food are woven into the story and it is quite a visual feast looking at the depiction of the many dishes. In this respect, I think Royal Feast wins over Yanxi Palace as it has this added dimension.
Wu Jin Yan gives a spunky portrayal Yao Zi Jin; one would say that it is an almost similar character to Wei Ying Luo of Yanxi Palace. In Royal Feast, Xu Kai has a more substantial role compared to in Yanxi Palace and he pulls off his portrayal of the honorable prince and emperor Zhu Zhan Ji.
Overall an entertaining watch!
