How big are the kids/adult portion in the restaurants that have kids/adult menus.
If you hunt down a post entitled "food photos" your question could be answered when you see the portion sizes that are served in various restaurants and you can decide whether they are big/small when compared to your usual portions
As you have been twice before, you realise that you cannot order a kids meal in a table service restaurant, unless you are a child. In a counter service restaurant it wouldn't matter. Where did you eat on your previous visits, did you find the portions too big?
