Definitely not a swanky or fancy buffet, but that's why you're getting such a discounted price to eat there.
They have the usual buffet "classics" like American, Chinese, Italian, Mexican, with a salad and dessert bar.
The food was comped, and even if it wasn't, I would still pay to eat here, but the service is horrible and the waitresses seem to make you fell like you're bugging them when you ask for refills on drinks or extra napkins.
Step it up Gold Coast, inexpensive doesn't mean poor customer service.
