Alej I think you might want to read the question again - plus Australian food is not just like America. Are you in London Joe's Mum? I know a couple of Austrian restaurants if you are.
There used to be a wonderful restaurant on Queensway. J�gerh�tte!
Unfortunately it was taken over by Chinese some years ago.
Not sure if the owners moved somewhere else...
But if you come to visit, I live about three hours from the Austrian border...
