It's tough not knowing your specific tastes...here are a few thoughts based on my experience,,,
Kouzinna on BW is wonderful. We loved the food, atmosphere and service. In fact we had a breakfast ADR and enjoyed it so much we changed one of our dinner adrs that week to go there for dinner...
Both restaurants at the Poly are great ... Ohana and Kona. Obama is usually tough to get an ADR, a but Kona may not be.
For something different .. Maybe Morrocco...we've been there a few times and enjoyed ourselves every time. Food is good the atmosphere is different and nice and they have a belly dancer for entertainment.
