Crowds clog the Mississippi Avenue sidewalk every weekend morning, lured by Gravy's rib-sticking homestyle breakfasts. If you actually want to eat here instead of just standing around, try the popular but less-crazed lunch hour. Burgers ($7.25), soups, a pulled-pork sandwich ($7.50) that holds its own with any in town and quirky salads (chopped greens, almonds, raisins and sliced apples, $7.75) make this breakfast stronghold a stealth contender for mid-day honors, too.
