What do I eat if I want to avoid getting fat at a Chinese restaurant buffet called "Mandarin" Buffet?

I was thinking maybe steak and salad but there salads use very cheap ingredients so I feel like I would be ripping myself off if I ate only salad at the buffet. I don't like their sushi cause they use vinegar in their rice which makes me feel like it's not as clean as other sushi places.
