This is not your standard BK. It is a Whopper Bar. I remember when I was there last time, they did not have all the items that the standard BK has. I can't remember if they had Chicken Nuggets or not.
I *think* you can charge to your room key, but I am not 100% sure. Hopefully somebody else can comment that knows for sure. Just wanted to let you know that this is not your standard BK.
