Cheeseburger Charley's seem like pretty simple fare, but this lively diner offers an interesting twist on the American classic. How about an all-beef patty grilled with mixed vegetables, or a black bean burger? What about a beefalo burger or a nice turkey burger? These are healthy alternatives, containing less than seven grams of fat per serving. Burger purists can still opt for the greasier variety of burger, and no one should pass up the fries. You can't be healthy all the time, can you?
