I am not certain what a convenience store is, though I can guess, but I will admit the look of natto is similarly off putting. Yet it belies a flavor so involute in its intricacies it is often written off as simply "bad" by the layman. Furthermore, natto has been linked to long life, increased health, and even improved memory well into old age! It truly is the most miraculous of foods.
