Hi Susanne ~
Fantasmic! followed by dinner is an excellent way to top off a magical day!
There is indeed a concession stand in the Hollywood Hills Amphitheater. They carry several items such as hotdogs, popcorn, pretzels, fruit, chips, nachos, glazed almonds and pecans, Smucker's Uncrustables. cotton candy, and frozen novelties. They also carry beverages including some alcoholic beverages. It does get pretty crowded before Fantasmic! begins.
You could also stop by one of the food locations at the Sunset Ranch Market located along Sunset Blvd. and grab a snack to take in with you. It may be less crowded and you are welcome to take food into the amphitheater.
Please feel free to visit us again with all of your planning questions. We are hEAR for you!
Wishing you minnie magical memories :-) Allison V.
