I've also had steaks from all around the world. One thing we should all be able to agree on is that there is no such thing as a great steak in Europe!
The US is a pretty big place and there are all ranges of steakhouses. Some have fabulous cuts, some not. Some are world class, just as in a great place in Argentina or Brazil, some are not.
I've never had a great steak in Asia-Pac. In fact I really don't like the beef in Australia.
