My favorite place for lunch is Don Don's in Melbourne. Not just because its yummy, but also because it is blindingly efficient. Through a small menu, efficient process, and massive energy you can cross the street, get a beautiful Sashi Don (picture below) take away, and be out on the curb in time for the next walk signal. I am not making that up.
They could probably be given the same analytical treatment given Starbucks Barista Heuristics, which I have to admit, also shares some beauty in efficiently producing happy snacks.
