I don't think what they eat is the issue, I've seen adults at Boma load up on the chicken nuggets and french fries. At a buffet, the food, no matter what it is, is available to everyone, I just think it's unreasonable, even for Disney to charge a 10 year old the same price as a grown man or woman. A buffet is all you can eat, thus why they charge the prices they charge but most 10 year olds will not consume near the same amounts of food as an adult. Of course there will always be some exceptions. My son has always eaten what some may consider adult food, frankly I consider it just food, the buffets don't distinguish certain foods for children only, it's all available for the taking. At 10 he would eat a small slice of Roast Beef and a spoon full of spinach and a dessert or 2, for that he should be charged as an adult. Un-like most adults, he woudn't go back to buffet 2 and 3 times. Of course he's 13 and 1/2 now, 5'11" & 1/2, look out!
