Robert is preparing a thrilling meal for 250 roller coaster enthusiasts at one of the country's top locations for thrill seekers: Six Flag's Great America! Robert is given just nine hours to create a menu that takes standard amusement park classics like hot dogs and funnel cake and put as many twists and turns on them as the Six Flags coasters themselves. Robert soon finds out that there is one special twist to this mission that will make this challenge even more difficult- no grocery stores! Hank Salemi, the president of Six Flags Great America tells Robert that he will be doing ALL of his shopping at restaurants and stands within the park! With over a mile of ground to cover and without the luxury of a real grocery store Robert finds himself on a ride he wishes he could get off of. Robert is quick to realize that to really make this food as thrilling as these guests expect he's going to have to find a way to sneak some key ingredients into the park and into his menu otherwise this mission may truly be....Dinner: Impossible!
