Firstly, I know every child's appetite is different, and every restaurant/cafe is different.
DD1 is 8, approaching 9 years old. Yesterday, we had her first experience over a childrens meal not be fully sufficient for her appetite. I thought the portion size did look rather small compared to other places. But it got me thinking... What age would you expect a children's meal to last until?
(Lastly... I know there are other restaurants where a children's meal is more than enough for many adults! Actually, DD sometimes eats more than me...)
