One thing you can always count on in Mexico City, and Mexico for that matter, is excellent roasted chicken. While popular with locals, the dish is often overlooked by foreigners in favor of flashy tacos, but you should visit this small, sidewalk eatery and try its delicious marinated chicken; there are also grilled vegetables and salsas to make your own tacos. Grab an order to go (which many people do) or take a seat on one of the benches backed up to the street.
