Chef Motokichi Yukimura's viral-famous take on the dish has made him an internet star — the term "Japan's most-famous omurice chef" has been used — and seen his eatery become a tourist destination. As of January 2024, it's no longer doing bookings in advance, in fact. Now, diners are only able to make reservations on the same day they're eating, and need a password that's placed on the restaurant's door each morning to lock in their seating.
Unfortunately, you can't always be lucky and by the time I arrived, the queue was closed for the day :(
