A Hawaiian luau is a traditional feast that celebrates Hawaiian culture and community. It often features a variety of local foods, including roasted pig, poi, and tropical fruits. Luaus are typically held outdoors, with guests enjoying music, hula dancing, and other cultural performances. The event usually includes the preparation of the pig, which is cooked in an underground oven called an imu. Luaus can be family gatherings or larger events for tourists, providing an opportunity to experience the rich traditions of Hawaii and its people.
