I want to visit Vienna.

1. I will go to the zoo at the Schonnbrun Palace. I read a lot about this place and I am sure that it is very interesting there.

2. I can attend the opera. It is believed that this is the best opera in the world. There are a large number of stars and popular people, I would take autographs from them.

3. I would just walk through the streets of this ancient city(or visit the Cathedral of St. Stephen).
