It’s about a diner in Tokyo that’s open from midnight until 7 in the morning, and the deal is the diner’s owner will make anything a customer requests, as long as he has the ingredients. There are a few recurring characters but generally each episode is about a new diner coming in and requesting a certain dish, and you find out why that meal is special to them and learn a little about their background.

It’s very wholesome and visually satsifying (especially if you like watching food being made).
