Note: This review contains NO spoilers
The main cast consists of the restaurant’s owner, Tenshu, and his waitresses, Aletta and Kuro. In terms of character development, the anime is repetitive and bit slow. The viewer does not get a full reveal of how Tenshu and his restaurant is able to transport to another world every seven days until the end. Even with that big reveal, it left a rather bland taste in my mouth because of how blunt or simple the explanation was. The characters with a bit more development to them are his waitresses. The explanation lacked depth as if the story asked you to, “just accept it.” Aletta and Kuro were introduced at different points in the story and, like any rational person, were wary characters of the restaurant until later episodes. They were quiet when first introduced but become more comfortable in Nekoya as the episodes progressed.
Isekai Youshoku was a calm anime that filled the viewer with content or could inspire others to cook and decorate dishes of their own. It ended the summer with a humble whisper rather than an exciting bang.
