In Australia, a souvlaki is kind of different to the traditional greek dish. What we have here can still be purchased over there, but it's not what you get when you ask for a souvlaki. You ask for something different, which I forget, not being a greek speaker myself. In Australia it can be purchased at any Fish and Chip shop and certain other take away food vendors. It contains lamb cut off a spit, chopped fresh lettuce, tomatoes if they are in season (out of season tomatoes suck as everyone knows), cucumber, yoghurt and garlic sauce, all wrapped up in a slice of pita. It's more than enough for dinner by itself.
