We've eaten at the Wave, and there's nothing wrong with it, but for us it was a bit unremarkable. It's partitioned off from everything, I mean, no view and no real ambiance. If I may recommend Kona Cafe for lunch at the Poly, I think you'd really enjoy it. The food is super good, and you are in an open area that connects with the beautiful tropical lobby. It's a short monorail ride away from MK.
