The prize-winning bacon cheeseburger from Michael's Genuine in Miami.

It's not lack of imagination that has caused this old-school-burger apotheosis. It's convergent evolution. Through painful trial and error, the burger barons have learned that the old ways are best. And yet some brilliant young chef may be thinking of a way to make a better burger, and not by piling pastrami on top or adding locavore cheeses that nobody likes. No, that young man or woman--who may already be out there, building a hallelujah chorus on Yelp.com--will find a way to do for the hamburger what the Koreans have done for fried chicken, what the wood-oven movement has done for pizza, what Chipotle did for the fast-food burrito. And when that happens, the nation will have a hero--and the Rachael Ray Burger Bash a new champion.
