I'm looking for a great burrito. I checked the board and lots of people have posted about breakfast burritos but not really regular burritos in Chicago. No fancy fillings, just good old chicken, beef, steak, etc., with some options of sour cream, guacamole, salsa...Not looking for gigantic brick burritos ala Chipotle's, just a tasty, well-wrapped package of deliciouness. Doesn't have to be at a restaurant, an order-at-the-counter place is just as good (and sometimes preferable!) Thanks for any suggestions!
