The food in the anime is as aesthetically presented as it goes. One of the unexpected food animes I've always wanted to mention was Sweetness and Power by Gido Amagakure.
Welcome to the world of Yokai! Natsume yuujinchou or Natsume's Book of Friends by Yuki Midorikawa is a breath of fresh air if you really like slice of life anime involving Japanese religious cultures.
The anime turned mystery novel by Honobu Yonezawa is a great example of curious storytelling. Every episode is enjoyable to watch even if you are not a fan of anime.
