The Frisco Burger is a cheeseburger sandwiched between two toasted Parmesan sourdough slices and topped with an extra tangy doctored up 1000 Island dressing (Frisco sauce) filled with sweet pickle relish.
What distinguishes a Frisco burger is that, instead of a bun, the burger sits between two slices of grilled sourdough bread. In addition, the burger sports two kinds of cheese and a delicious "Frisco sauce," which is comprised of 1000 Island dressing, French dressing, ketchup, Worcestershire sauce, and an extra dollop of sweet pickle relish.
