what is your favourite Place?

I have never been in the US, and I would really like to visit Vegas, New York City, San Francisco, the Grand Canyon, Hollywood, Niagara Falls... lots of places. But I think the first one on my list of places to visit is the Taj Mahal.
I haven't had the opportunity to travel around the world too much, but I have been to Vienna (the capital city of Austria, in central Europe) and I have to say I really enjoyed my stay there. It's a gorgeous city...
