PANAMA CITY — The red glow outlining the giant triangular charcoal briquette on the corner lot of Harrison and 13th Street is about as neat as it gets at Jerry’s Burger Company. Messiness — juicy beef patties, golden buttery buns, gooey cheese sauces, savory seasonings — is the main thing on the menu. The restaurant’s co-owner, Jerry Pipkins, said it’s all a part of delivering a burger experience like none other.
