RE: Chicago burritos
Sorry Buckaroo, I don't usually hang out in the Mexican Food Forum and your query must have gotten bumped out of the current topics section pretty quick. Anyway, as long as we're here, I do have some ideas on the subject.
For a more casual carry out experience, try any of the "Burrito House locations around town. I usually got to the one on Addison just east of Kedzie or the one on Lincoln Avenue a little south of Addison. They serve two sizes, a junior or a king size. Due to my advancing age and dwindling metabolism, the junior is more than enough for me lately. They use very fresh ingredients, generously applied. One caveat: a burrito with "everything" does not include onions or cilantro unless you specifically ask for them.
For a sit-down meal try "Tecalitlan" (pronounced "TECK a leedle ON") on Chicago Avenue about 3-4 blocks west of Ashland. Back in the day when I worked downtown, a group of us made Tecalitlan a weekly stop. They start you off with chips served with an outstanding version of pico de gallo. Then my buddy and I would get a steak burrito and an avocado burrito and split them. That way we could say we'd gotten our meat and vegetables that day. They serve their burritos one size fits all, somewhere between Burrito House's junior and the football sized burritos served in so many places. As I recall, lunch at Tecalitlan was so filling I rarely ate dinner at home that night.
BTW, although I don't recall ever eating there, I've also heard good things about La Pasadita, mentioned above.
