I have been a long time fan of Chipotle and always have a great experience when I visit. Its a go to place when I'm watching carbs and when I'm not, I LOVE their chips! I could eat a whole bag by myself and that's probably what's caused me to diet in the first place :) You can lesson the calorie blow by ordering the kids sized bag of chips. It seems to come with 15-20 chips which is a more waistline friendly portion if you have to have them.
If you want something that satisfying and doesn't kill your diet, try a bowl with no rice or beans but get a scoop of chicken AND Steak. The extra meat really adds to the heartiness of the bowl and it feels like a treat. I also get mild salsa (pico), sour cream, cheese and the guacamole depending on how I'm feeling that day. If its a diet splurge day, I'm adding the sweet corn and tacking on a bag of chips!
