We went to The Wave at the end of October and had a horrible experience. The food was decent but the service was horrendous. The server was not attentive then she got chatty with a huge party, having conversations on top of taking orders. All this after we had asked for something. Then she managed to bring out a tray with all their drinks and toppled it on multiple people in their group. We waited forever for her to come back to get our dessert order and So we asked for our check and skipped it. It was not a good experience for us and I don't see us going back. Even if not for the service, the food was just meh.
In my opinion Kona is underrated. We have eaten there 4-5 times and always happy with it, especially their lunch menu. I can't recall a bad meal or service there. It's kind of in the open so it's a little loud but no worse than Ohana.
