I thought that the food quality was very poor. The fish egg roll wrapped in nori was not wrapped, and the fish soup was only the fatty brown part of salmon (no other type of seafood) and too salty. As well, I asked what the BBQ fish was and was told they did not know. It was a sardine fish with head cut in half. Worse, my friend and I ordered a couple of things when we sat down but the staff (because there were 4 young Japanese men serving us) kept trying to take them away.
There's no al a carte menu. As well, you have a 90 minute maximum and are told on the menu that you'll have to pay for anything you do not eat. Considering there are no prices given b/c they only do all-you-eat, who knows what they would charge.
The decor was very nice though and if you are going out with a big eater, this might be a great choice.
I went on a Saturday afternoon in November at 12:30 pm, and there was no line up. By 1 pm, there was a line up of about 10 people.
