Hello,
I went to the United States in several cities and places. (New-York, Los Angeles, San Francisco, Chicago, Washinton, Boston, Miami, Las Vega, Seattle, New Orleans ext ...
My favorite city is New York because there are lots and lots of shops, there were some spectacular posters, There were a lot of people, so a lot of noise but it gave the impression of not being alone so it's a side positive, and the restaurant offered succulent food. On the other hand the city that I liked less is New Orleans because the place where I am to go there were not many people, it was too quiet and I do not I didn't really have fun there.
Good Luck
