Hi After The check point there is a Starbucks from where you can have a snack for less than $10. Just keep your receipt if you are willing to vist The Universal studio. Have a Fun! Eh !
They search back packs etc for Any items that are not allowed into the park. So as long as you are not bringing in weapons are anything like that if you bring in a backpack or like a diaper bag you can put snacks and stuff and you should be fine. Your bag will be sent through an Xray machine.
Cookies, sandwiches, water..
Its more liquids that they are concerned about. We brought a diaper bag full of chips, crackers and water and had no isses
You can have a small cooler with 2 waters and some small snacks
