Believe me, compared to the fast food at the Richmond station kiosk, the ones at FSS are a delicacy.
For fast-food-while-travelling-by-train addicts, might I suggest the South Yarra Station kiosk on the concourse there?
Hamburger with the lot: $3 and worth every cent. Chicken Schnitzel burger: $3 and usually damn good. Egg and Bacon toasted sandwitch: $2 and great for hangovers
Best value rail station takeway in Melbourne, no contest.
As for the dim sims etc at Flinders Street: I'd be *delighted* if they got rid of the platform kiosks. Why? Well, if you've ever boarded a train there and found yourself in a group of four seats where the other three people are stinking the entire train out with vinegar, soy sauce and whatever the hell it is they put in dim sims, you'd want them gone too
