Winstead's Steakburgers has been named Food Network Magazine's the Best Hamburger in the state of Kansas. Famed food critic Calvin Trillin also considers Winstead's to have the world's best cheeseburgers. And, it was one of the first drive-in restaurants in the country. With those impressive accolades, the art deco/streamline moderne restaurant was a must visit for me when I traveled to Kansas City. I ordered a single Winstead with "everything," which includes mustard, ketchup, pickle, and onion. I also added cheese. A strawberry shake topped off the meal. A solid, tasty burger? No doubt. The best burger in America? No chance. There was some good burger seasoning, but lack of melted cheese and a lackluster bun knocked a few points off for me. Grade: B
