I love taking people to Tropical Farms, also known as the Macadamia Nut Place on the Windward Side of Oahu. It's a different world compared to the rest of the tourist stops. Sure, there are still the Robert's of Hawaii busses filled with Japanese, Chinese, or Middle American tourists (fun fact which may or may not be true - the average American bus tourist takes up at least twice the space of the average Chinese or Japanese tourist).
