It's great! Just a heads up (from personal experience) : every time I have gone to Royal there's been a long wait. I've walked to Lucky's Last Chance down the street, had a drink or two to pass the time. Usually works out well.

The Izakaya is walk in only and does serve a fair amount of sushi but izakayas traditionally only have cooked bar food. but Royal Sushi, the sushi bar.in the back is only omakase and reservations are impossible to get
