"Philadelphia’s bread, cheese, and meat prowess is well established, and not just in the cheesesteak department. Philly’s hottest burger isn’t from a casual smashburger stand or an old-school tavern, but from a tasting menu spot that messes around with koji butter and firefly squid. The burger is only available as an add-on on Mondays, and it’s not too complicated—just as great burgers should be. Two beef patties with crispy edges and perfectly pink middles are topped with Cooper Sharp, pickled red onions, and a slathering of everything-seasoned mayonnaise, all between toasted sesame seed buns. Even after a four-course dinner, you’ll polish it off and be sad it’s over." - anne cruz
