served with fries

Chicken nuggets, mac and cheese, a burger, grilled cheese. Maybe cheese pizza if the place is feeling generous. You can walk into a diner, a Mexican restaurant, and a Thai place in the same afternoon and get handed the same menu three times.

The usual explanation is that kids are picky. That's part of it, but it's not the main thing.

The real reason is the kitchen. Every item on that list is already in the building for other purposes. The fryer is running, the flattop is hot, the cheese and bread are in the walk in. A kids menu built from those ingredients adds zero new inventory and zero new prep. Add one item that requires its own ingredient and it has to sell well enough to justify the waste when it doesn't.

Kids meals are also priced low on purpose. They're not making the restaurant money. They exist so a family with a seven year old picks that restaurant over the one down the street. A loss leader doesn't get an interesting menu.

Then there's the loop. Kids get offered beige fried food, so beige fried food is what they learn to expect, so that's what parents order to avoid a fight, so that's what restaurants keep making. Food neophobia in young kids is real and peaks around preschool age, but it's not a fixed trait. It responds to repeated exposure. A menu that never exposes anyone to anything new isn't testing that.

What actually changed was the drink. Davis, California passed the first local ordinance in 2015 making water or milk the default beverage with kids meals. Other cities followed, including Santa Clara County, and in 2018 California became the first state to pass it, effective January 2019. Parents can still ask for soda. It's just no longer what shows up automatically.

That's a smart piece of policy design because it changes the default instead of banning anything, and defaults do a lot of work.

Except follow up research found restaurants weren't reliably complying. One study of fast food in low income California neighborhoods found that on online ordering platforms, under six percent of observations matched the law's strictest reading. A law that lives on a menu board doesn't automatically make it into DoorDash.

The drink is the part that got fixed, sort of. The food didn't, and probably won't, because the reasons it's that way are about kitchen costs and not about anyone's beliefs about child nutrition.

Which means the most useful thing to know is that the kids menu is usually not the best option at the table. A half portion of something off the regular menu, or an appetizer, is often cheaper per unit and less fried. Most restaurants will do it if you ask.

Worth noticing next time you're out. The kids menu isn't a recommendation. It's whatever the kitchen already had.
