Took my parents out for one final meal of the year to an unagi restaurant in Ginza this past weekend.

Arrived at 12 noon. Already a long line and waited for about 20 minutes. It’s a no-reservations restaurant.
The link below will take you to the “main” branch as opposed to the “Ginza” branch of the unagi restaurant. There is not much info on the Ginza shop on the web and this one is better than others.
