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.

Midnight Diner ran for 3 seasons. No new episodes are scheduled.
