I ordered "Japanese Pan Noodles" at the Noodles & Company outside Rochester, MN (visit the website and click on "Asian" for a rather offensive anthropomorphization of a piece of penne, which is not even from Asia) and was delighted to find exactly nine slices of shiitake in my dish. Approximately half a mushroom! The sweet brown stir-fry sauce somewhat obscured their taste, but they nonetheless added chewy intrigue to the meal.
