The 2009 champion has fallen. Round 3 of the Burger Battle turned out to be a tense throwdown between Charley's and M&O Station Grill, which won the Readers' Choice bracket two years ago. This year, the Cowtown matchup was neck-and-neck throughout, but in the last two hours of voting, Charley's got out the word on Facebook, and its fans surged to thrust it into a spot in the readers' Final Four. So it's adieu to former burger king M&O. Charley's Old Fashioned Hamburgers will join Tommy's (which bested Chubby's), Kincaid's (sorry, Twisted Root), and Fred's (see ya next year, Pappas). It's a killer Final Four: Now who do you want to advance to the finals? Be sure to cast your votes here! NOTE: to vote in the Final Four, click on the "FINALS" tab in the bracket.
