Can't tell you if the menu is up to date as it was last year that we were at Jiko, but other than that, the answer to all your questions are basically yes, lol. It is basically quiet and romantic, softly lit, pretty not busy visually, generally more of an upscale feel and definitely a more adult feel compared to other Disney restaurants. While the entrees were not exactly "African," the appetizers and items "from the cooking place" were closer to Boma type food. I had the pork, DH had the filet and mac and cheese. We both tasted each other's food, and not only was it really good, it was definitely of the quality you would find at an upscale restaurant in "the real world." Jiko is a great choice for your anniversary dinner. Since you are staying at AKL, if for some reason you don't get PS's for the restaurant, you can give them your name and they will call you in your room when your table is available if you want. People dressed nicer than the normal "park casual." Some of the other diners where dressed in dresses and suits, but anything except shorts or jeans would probably not stand out as unusual. DH wore a polo shirt and dockers and I wore "dressy" capri pants and a blouse. We were perfectly comfortable with that.
