2. The Rouge Burger, Rouge, Philadelphia, PA
In a restaurant famous for its food, this burger stands out. It’s 12 ounces of a custom beef blend patty, caramelized onions, and gruyere cheese on a brioche challah bun. Patrons are free to add any other toppings they want. Attempts to change the bun met with outrage from fans of this long time Philadelphia favorite.
