Osaka II is the modern version of Osaka I, and it's a true Japanese all the way. Over a 100 dishes of all kinds, not just sushi, sashimi, teppanyaki and tempura, but also a lot of stuff you have never heard of, luckily all explained in pictures. A modern, slick interiror a-la-real-Japanese, fully native staff. It could also be the best value for an authentic Japanese in town - at 12-16€ for all-you-can-eat (on a conveyor belt moving past your table) you really can't complain, considering the quality of the dishes.
