Was just there a couple of weeks ago.
I found the staff to be excellent, the decor is outstanding and the view out of the windows very nice.
I had the sirloin over the macaroni and cheese. Appetizer was the wild boar (excellent). The sirloin was very tasty, but much smaller than I would have expected at the price. The mac-n-cheese was very good, but again the portion size was quite small. We also had the fish (I forget which one, but it wasn't the salmon). It was served with a creamy sauce and just wasn't what we expected. It was no fault of Jiko, just a poorly placed decision to go with this dish.
Overall, a very good experience and do recommend at least 1X. Personally, I had a much better steak/fish split meal at Flying Fish at Disney's Boardwalk. In fact, the service at FF was impeccable.
