I'm an isekai junkie so my score is slightly biased. Objectively probably a 6.5 at most but I rate on enjoyment. Also, the manga got axed so the ending is much worse than it should have been.
The concept is pretty unique as far as isekais go, but the execution could have been a lot better. They don't bother with much explanations and the power system is just convenient as usual. The mc becomes a masterchef Gordan Ramsey couldn't complain about because plot armor I guess. The characters are also very 1 dimensional with little development. The best part is probably the art. It's not the best but it's pretty cute and consistent.
Overall, this was an alright read imo but there are just so many more interesting manga you could read instead.
