You will not see too many Dominicans in Atlanta, at least, they are not as visible as Mexicans or Brazilians. I visit marietta and kennesaw every 2-3 months and I have hardly ever come across a dominican in any store or grocery store. All I see is a million mexicans, some brazilians and maybe some from south america. There are a few dominican beauty salons in the area and I think I have seen a dominican restaurant in kennesaw. I am sure if you go there, you will meet many dominicans who frequent these establishments.
