ELI5: Why do kids menus at restaurants have age limits?
gpt
Kid's menu's are what's called a "Loss Leader".

It's something sold at no profit or even below cost to entice customers into the store, knowing that they'll spend more on other stuff once they're there.

Nobody brings a kid in to eat off the menu and just sits there.   They get food for themselves as well.     When you're talking kids, that typically means a family night out.   Mom and Dad have full priced meals, perhaps an entree, couple of drinks.     It's the same they'd spend if they were on a date with no kid.     The kid menu is just something to get them in the door.     Without it, they'd just stay home with the kid.
