I can't keep track of all the places you can go to. IMO, the best fast food burgers are freshly griddled, with a slice of cheese. A good pickle is the best topping. Griddled onions also acceptable. A good sauce is a nice option but not mandatory if the cheese is melty enough. The bun should be griddled, hopefully in butter. Missing any of these components and your burger is second rate at best.
