Chipotle is a fantastic place to order a cheap, humongous, delicious burrito made any way you like. I always order the steak burrito, with no beans, chili corn and hot sauce, sour cream and cheese. Sure, it probably takes up most of your maximum calorie intake (the burrito wrap itself is about 400 cal... but you can order the bowl without it), but I believe it is worth it every once and a while. Also, Chipotle often has promotions where you can buy a burrito, and get one free on a later date (e.g. buying a gift card before Valentine's day), or even a free one if you dress up like a burrito on Halloween. In addition, the management are very generous. One time, my boyfriend and I had to wait 5 minutes for the steak to be finished cooking, and the staff just gave us our two burritos for free!
Pros: The burritos DUH!, the friendly and accomadating staff
Cons: Burritos are calorie intentsive
