>>358586It is a TV drama based off a manga about a restaurant in Shinjuku run by a master that is open between 12AM and 6AM. Uniquely, besides a simple menu, the master will cook anything his customer orders, even not on the menu.
While the master is a central character, each episode is focused on customers that visit the restaurant and orders something unique, which is related to their story. There is no overarching plot and a new customer shows up about every episode, but there are also regulars of the place that show up often.
The ambience, the food, the characters, all make up for a comfy 25 min per episode. In the end of the episode, they even show you how to prepare the featured food of the episode.
