We just had lunch there, and while it was good, it isn't something that we'll rush back for. There were too many dishes repeated (with slight variations in theme/spices) like chicken and green beans.
The food was across the board, not up to temperature. I really dislike cold food, and that was what we found at the buffet.
It was messy too, but that is more the guests than anything. However, WDW is known for keeping up with that and maintaining the buffet. I asked some quesitons of the CMs who were working behind the buffet but couldn't get answers to the content questions. A little disconcerting (although not allergy related, I do have dietary restrictions).
I'll stick with Jiko, thanks.
