I like food, and I also enjoy fantasy stories. So this series seems interesting to me.
Something that makes me wonder is that, since it's a Korean drama (or Dorama), it might be based on a previous manhwa or light novel. I should probably take some time to look for the original source material, because I've found some of these works to be incredibly entertaining.
