Onomichi Kamisama no Kakurega Restaurant

Ayame moves to Onomichi, where her late grandmother used to live, before entering university. By chance, she visits a restaurant called "Maneki Neko" at a certain shrine. However, the restaurant has no menu. The owner, Kamui, claims to be able to recreate dishes associated with the memories of those who visit the restaurant. Ayame is skeptical, but Kamui hands her a dish that only she and her grandmother should know about... Ayame ends up working at "Maneki Neko" for some reason, but it seems that it's not just "humans" who visit the restaurant--!?
