In ShortSince 1977, the aroma of fresh-baked batter has wafted through America's malls, luring millions to the storefronts of this mea-confectioner. A single pane of glass stands between waiting customers and their objects of affection--chewy cookies ranging in flavor from original chocolate chip to oatmeal walnut raisin. Below them, the store's popular cookie cakes are displayed with custom-frosted designs, not to be outdone by a large selection of dense brownies and specially packaged gift collections.
