"In terms of sandwiches you literally could not find anywhere else, Papi Sal’s delivers in spades at White Owl Social Club, where the former food cart pops up. Philadelphia meets Puerto Rico whether it’s in a pernil-and-Provolone “jawn” with broccoli rabe, or the vegan cheese chopped “jawn” with oyster mushrooms and guava barbecue sauce. Keep an eye on the Papi Sal’s Instagram for secret menu items and specials, like the chipped prosciutto and sofrito mayo Old Italian." - Alex Frane, Janey Wong
