If you are visiting the home of the notorious 7-pound burrito, you can certainly expect to get your money's worth of great food. Jack-n-Grill in Jefferson Park is a family owned joint serving all of the Mexican classics in massive portion sizes. Even if you opt for a burrito weighing in less than 7 pounds, you still may have to take half of it home for leftovers. Jack-n-Grill delivers not only on size but also flavor, as each dish is both reminiscent of traditional Mexican food and well-executed.
