Let's see I went to Hawaii when I was 21 years old and still remember how much I enjoyed the Parasdie Cove luau. As a side note my mom enjoyed it too. She was born on the big island of Hawaii and we have been to many luaus in California. I make a heck of a good Crockpot kahlua pork.
We did the Polynesian Cultural Center to but that wasn't a traditonal "luau" it was more of a Polynesian Buffet.
To me a Luau should feature the whole pig (kahlua pork) being pulled from the ground. The food items should in Chicken long rice, Lomilomi Salmon, Hawaiian style Macaroni Salad, Haupia, and poi. Laulau are also very good. The enertain has to include fire dancers. Enjoy!!
