The best thing about Duke's is that it's very easy to walk to for dinner when staying at the Westin Villa on Ka'anapali Beach. It's so nice to be able to drink and not have to worry about driving.
There are two seating areas – an outside bar menu with burgers, salads, sandwiches, etc. and a more formal and expensive dinner menu with fish, steaks, seafood, and pasta. You can have the dinner menu in the bar area but can't have the bar menu in the dinner area.
We've eaten in both places and the food is always very good. In the bar area, we had excellent grilled steak tacos, teriyaki chicken & ribs and macadamia fish sandwich. In dining room we had great local fish. On our last visit, we ate in the bar area and had a great light dinner with drinks for $60.
