Very quiet and clean. I've only been there for lunch. Though the restaurant is not big, they have a very good selection of food. They have sushi, raw and cooked, a salad bar, with some Korean dishes too, and then tempura, as well as noodle soups.
The thing I like the most is their seaweed salad, it's got a hint of sesame oil and soy, refreshing and delicious. I also like their tempura and their cooked sushi since I don't eat raw fish.
