I feel that this little stall at the bottom of the ramp in the Adelaide Railway Station has been here forever. I still remember when it was a Donut King. Anyway, it is a really cheap place to grab a snack on the way home, and they don't just do donuts (as the name implies) but also hot dogs, and even chips (and their chips are actually pretty good). They also do tea and coffee if you're the type of person that needs a good pick up in the morning. Oh, and the prices are also really good, though they do not have a huge variety of tea, just the basic. Unfortunately, since I don't drink coffee, I really can't comment on that, but I can say that they do use filtered water which does take the bite out of the tea (if you know anything about Adelaide that is).
