Bob Olguin knows his chiles. He should; New Mexican cuisine is in his blood -- he owns and operates the restaurant his father started in honor of his grandfather. So, it's no surprise his Green Chile Cheeseburger was ranked number 7 on GQ's National Top-20 Burger List. Bob's restaurant, Manny's Buckhorn Tavern, started by dishing up New Mexican favorites to locals but now caters to visitors from far and wide, and the praises keep on coming -- especially for his famed Green Chile Cheeseburger. So the question is: can Bob's burger beat the heat that Bobby brings down to New Mexico on this episode of Throwdown?
