The City of Davis says it's taking a stand against obesity, by making milk or water the default drink in kids' meals.
The ordinance passed the Davis City Council unanimously Tuesday.
It requires restaurants in the college town west to include milk or water in kids' meals unless parents specifically request a soda for their child.
The rule goes into effect Sept. 1.
Advocates say studies show that parents will opt for the healthier option, if presented with a choice.
They also say the ordinance is the first of its kind in the country.
