I have not been to the Luau, but I can tell you Tchoup
Chop is excellent! We have eaten there twice now, and the last time (May) the food was even better than the first time (January). All four of us loved our meals, from the appetizers through the desserts. The service team we got was just incredible, so I left a nice tip ($50). A couple of weeks later, I received a postcard from the team leader thanking us for stopping by and asking us to request his team next time we came in!
