Poor customer service, food is okay not amazing. But my biggest complaint is having the tip bundled into the bill. I should be able to determine how much I want to tip especially if the service is terrible. In addition there is a 5% surcharge for paying anything other than cash, that is ridiculous. I have never been to a restaurant which has done this.
Also sashimi / food quality goes down hill after the first round of orders and continues to diminish in quality the longer you stay as if they are rushing you out.
