Going to Great America with my preteen daughter this Sunday - we'll both love the roller coasters but she has sophisticated tastes and won't like the crappy, overpriced junk food there any more than I will. They don't allow you to bring food into the park. So... any suggestions? They have a picnic area outside so could lug a cooler in the car. But if there's something chow-ish that's walking distance from the gates (so we don't have to park again), would love to try that. Or if there's actually something good in the park that would be useful to know.
