What is the largest amount of food you have seen/heard about someone eating at one sitting?
Personally I had seen one man pile 9 plates of Chinese food (mostly cheap noodles and chicken). When they eat by themselves, I think they eat a lot more. When they are with friends, the social pressure keeps them from gorging too much. My waiters had said a larger number, but they might be overestimating. No one can really eat more than 2 pounds.
