I want to clarify by saying, I myself have yet to have a bad KI food experience to where I can't finish what I eat. I've enjoyed everything I've had at KI. However, I will say the food isn't as good as it was under Chef Major and over the last few years, I have seen numerous complaints about food being undercooked, food being left out under the lamp too long, food being overcooked, among other things that really take away from the guest experience. While some of that stuff is at the fault of the food employees, the fact it continues to happen despite all the complaints comes down to training/management which falls on the executive chef.
Things like portion sizes, no ice in the machines, watered down drinks, machines being out of drinks is a budget thing while things like properly preparing, cooking, and/or storing food has nothing to do with budget. That's a management/training issue.
