Depends on where you live. Most of the asians are vietnamese or from the phillipines here (at least the ones that like to go to the casino).

It's probally a waste of time. Even if they are chinese they are probally speaking their own dialect and not manderin or cantonese. (every little region in china has it's own dialect, if a group of people are all from the same region they usually prefer to speak that langauge if they can)

I can imagine if you are a coastie you probally will see more chinese people than in the midwest, but you'll probally find tons of other ethnic groups as well (especially the west coast).
