After looking through London, Paris, and Tokyo I decided to see what was written about the United States. It turned out to be an interesting read because things I didn't really pay much attention to were mentioned like what accent is portrayed in mass media and types of alcohol served at restaurants, if any.
My favorite facts about our culture:
"A degree of romance is attached to non-American English accents, and people may be friendlier to you because of yours."
"Unlike much of the rest of the world, tipping in America is essentially mandatory for polite patrons -- and, indeed, tips often form the majority of a worker's income."
"California wines are some of the best in the world, and are available on most wine lists in the country."
"At the college or university level the United States, by almost any measure, has no peer."
Reading about your own culture can be almost as compelling as another one.
