Osaka I is a traditional version of the modern Osaka II. They serve the same menu - over a 100 authentic Japanese dishes explained in pictures, they have the same all-you-can-eat buffets, only this place is for the lovers of a traditional interior. Woodwork, partitions between tables, and those cute Japanese cabins for private dinners. They are also very proud of their teppanyaki show - grilling it in front of you while you watch.
