Fia Fia, but if you can't make Tuesday, Chief also has another luau ("Chief's Luau") at the waterpark every Sun, Mon, Wed, Thu, and Fri.
Here's a thread with additional information, including waterpark address (it's the one near Ko Olina):
A friend of mine is flying to Oahu in a few weeks and was asking me what I know about Luau's. If my memory serves correctly, Fia Fia used to be presented on Tuesday nights at Marriott's Ko Olina resort. Does anyone know if Fia Fia is still putting on a show @ Ko Olina in light of the Covid...

There's also Paradise Cove...while the food is really good, Chief's show is much better.
