Is this not a place you pay for all you can eat? That answers your question. All You Can Eat.... Where did you come up with such an idea. People get kicked out of places for fighting or being to loud or stealing what does not belong to them. This is a common sense question.
Isn't a buffet all u can eat? Are signs POSTED limiting your trips to the food line or plate count? They might refuse to seat you next time you come in, but they might not want that legal hassle. Go for it.
