I can't suggest anything at nearby hotels. but will second the recommendation for Lineage. Even though it's a small chain, we also liked Monkeypod Kitchen. As far as the on-property restaurants go, we did enjoy the Chef's Table at Ka'ana Kitchen but like
beachfan we were disappointed with Morimoto and would not go back.
Lineage, definite yes. Also Spoon and Key - not open every night.
I really don't think Monkeypod has good food, personally. It's bar food, and not great bar food. But the Mai Tai is for real.
