on the website for kids meals, it does not list a beverage.
i will look more for you
this i did find for options with the kids meals:
Trans-Fat-Free Option!
Universal Orlando Resort provides healthy and delicious dining options for you and your family while you visit Islands of Adventure and Universal Studios. Many of our restaurants and food locations located in our theme parks cook with trans-fat-free oil.
And at select locations, side options for adults and children include healthy choices. At those locations, Kids Meals come with a choice of fruit or trans-fat-free fries. Adults can select from either a side salad or trans-fat-free fries. When you arrive, please see the theme park guides for more information.
