Season 1 synopsis: "Set in a small restaurant in the corner of a shopping district. The unusual eatery is only open after midnight, and its standard menu consists of just a single choice. However, the customers still come for the amusing chatter and the proprietor's willingness to cook any dish that they request. This drama depicts the lives of the restaurant's patrons, including a yakuza, an unsuccessful actor, a group of office ladies, a newspaper delivery boy, and a stripper. --Tokyograph"
Cast & Credits
You could watch season 2 without watching season 1, but I think season 2 may not be as good if you don't experience the connection that develops through season 1.
It follows the same formula as the first season. The story centers around a cafe/diner that is only open from midnight to until breakfast. Each episode focuses on the experiences of an individual patron and can be watched independently. However, the episodes in season 2 are slightly more connected than season 1 (just barely).
The mood is similar to season 1: melancholy and bittersweet.
Season 2 really feels like it may be the end of this drama, which kinda brought tears to my eyes.
It's quiet and reflective, so you have to be a person who likes that sort of thing and in the right mood to watch it.
