There is a difference between "greasy spoon" burgers and the kind you'd find at a place like So-Long that everyone raves about. 9/ 10 if I'm in the mood for a burger I'm thinking greasy spoon.
Obv, Town Topic, and even places like Winstead's in the KC area. Wichita has some great burger West Street Burgers, Bionic Burger, Walt's, etc. West Street is probably my fave.
