While searching for nutrition information for my carnitas soft tacos so I could fill out my daily fitday.com food log I came upon ChipotleFan.com. They have a great nutrition information calculator -- something Chipotle.com lacks. My tacos = 912 calories.
But the best part is the Find your Burrito Soulmate feature.
There are 40,960 ways to get your meal at Chipotle. The person who gets the exact same meal as you is your Burrito Soulmate.
