Racks of ribs, DIY taco kits, and oysters and seafood aren't typically what you'd think about when it comes to food at the ballpark. At Citizens Bank Park, these are some of the foods fans have eaten while cheering on the Phillies. At Citizens Bank Park and 26 other Major League Baseball stadiums, outside food is permitted as long as it is sealed and fits inside a stadium-approved bag. For the Phillies, this bag must be no bigger than 12 inches by 6 inches by 12 inches, according to a Northeast Times report. A local influencer by the name of “the Hippie Meathead” once brought 60 oysters into Citizens Bank Park by shoving them inside hoagie rolls, in their shells, and wrapping the rolls in aluminum foil.
