There was an article in the local rag "Courier Mail" quite a few months ago about Indian restaurants in Brisbane. Can't find it now but it was one of those fluff pieces like "the best 10 fish and chip shops", "the best 10 cappuccinos" etc that they trot out on a slow news day.
One of the comments online was "why didn't you put in the xxxxx restaurant, they do a true onion based sauce that.....". And I think it was from a UK Ex Pat ... I'll keep searching and see if I can find out where it was.
