If you are going to eat breakfast, and you are at the Poly, Kona is a nice place to eat. I agree that service is slow. But the pressed pot of 100% Kona coffee is a nice way to wake up. The fruit plate inside the bowl carved out of a pineapple is great (according to the DW), and the Tonga toast is really good.
However, I wouldn't go there if I wasn't staying at the Poly and at this point in my life, with a DD1 and a DS5, we would only travel to a resort for a character B-fast.
