The buffet restaurant at Disney's Aulani resort offers a wide variety of locally produced items, as well as familiar dishes from stateside and the rest of the world. You'll find sustainable Hawaiian seafood, Asian selections, familiar grilled meats and vegetables, and a kids' menu. If you have children, plan months in advance to get a reservation for the Character Breakfast, as it's only offered on select days and is always sold out. An a la carte menu is also available.
Arrive early for dinner and have a drink at the adjacent Olelo Room, where the staff are fluent in Hawaiian; you can get a language lesson along with your libation.
