We ate at Kona for dinner based on all the great reviews and the fact that it was a "trip must" for so many. However, I really dislike saying this, but I was disappointed.
My husband had the prime rib, and I had the terriyaki steak. The steak was not good. The sauce was fine but the steak wasn't. My husband's prime rib was not as tender as other prime ribs that he has had (ok, it was tough and not very flavorful). He said it was basically, "ok". The sides were ok at best.
For appetizers he had the pot stickers which he liked. I had the crab cakes which were fine - not outstanding or memorable but more tasty than the steak.
The bread and butter that they serve prior to the meal was excellent. It was warm and fresh and had a great flavor.
We didn't order dessert because we were overall not really pleased with dinner. I do want to mention that the raspberry smoothie (non-alcoholic) was tasty. The service was fine. It's loud in there due to it being opened up to the walkway and waiting area for Ohanas, but every restaurant we went to was loud - no fault of theirs.
Would we eat there again? If we stay at the Poly, I will book an ADR there again. This time I will eat the fish or chicken. It could be that it was a bad night or a new chef or something. I'm usually willing to give a restaurant another chance when things were just Ok. Normally it may be very good. Actually I'm sure it is normally very good due to all the reviews.
