Chipotle got its start in Colorado, and although this homegrown chain is now running with the big dogs, it still serves up one massive puppy of a barbacoa burrito. To create the classic, Chipotle braises beef in a liquid rife with chipotles, cumin, cloves and garlic until it softens and shreds and absorbs every bit of flavor. The meat is then wrapped in a jumbo flour tortilla along with pintos, Chipotle's signature cilantro-lime rice and much-needed sour cream to cool the heat. If your stomach can take it, throw in the fiery tomatillo salsa. The winner and still the chomp.
