Yes, you can bring sandwiches into Universal Studios Hollywood, provided they are for personal consumption and are not packed in large, hard-sided coolers. According to the park's current 2026 food policy, small snacks and "food required for special dietary needs" are permitted. You can pack your sandwiches in a soft-sided insulated bag as long as it does not exceed 8.5” wide x 6” high x 6” deep. For those with families, this is a popular way to save on high theme park food costs. However, you cannot bring in large "picnic lunches," glass containers, or alcohol. All bags are subject to X-ray and manual inspection at the security checkpoint, so it is best to keep your sandwiches in clear reusable bags or wrap to speed up the process. If you have a larger cooler, you will be asked to leave it in your vehicle or store it in a locker outside the park entrance, as they are prohibited inside the gates for safety and space reasons.
