I ordered 3 dishes here. Flamed salmon sushi, kakimayo, and tempura.
It took 10 mins for the first dish to be out from the moment I ordered, and I could say it was relatively fast because there were so many people.
Flamed salmon sushi was cold, and I had to check it was really flamed.
Kakimayo (oysters with mayo+cheese) had too much mayo and cheese in it. I barely tasted oyster. Tempura was alright, but it was average.
I believe people go to this place because of the atmosphere, which was indeed amazing.
However, I have tasted better Japanese food. I really did not see anything special about this place.
