RE: Italian, Chinese, Mexican, Thai and Japanese
Not to disanswer the question, but to add a bit to it, perhaps.
Buford Highway in the Chamblee/Doraville area NE of downtown Atlanta must have 500-600 ethnic restaurants in a six-mile stretch: Mexican (from virtually every state of that country), Salvadorean, Thai, Vietnamese, Korean, Hmong, Laotian, Guatamalean, Hondourean, Haitian, every conceivable style of Chinese, Burmese (the country is now known as Myanmar), most every style of Indian, Sri Lankan, Japanese, Cambodian, African (of many areas), and practically anything else you can - or maybe can't - think of.
Elsewhere in Metro Atlanta there are all manner of Brasilian, Russian, Slavic, Bulgarian, and even Bosnian eateries. None of this is your standard Roadfood, but instead is something to experience with great joy. We all have a great deal to learn from each other.
As close as we come here in Athens, Georgia is a former Mexican restaurant run by people from the Indian subcontinent who "changed format" to Indian foods and are now doing a rip-roaring business where before they were slower than high noon in downtown Robinson, Georgia 30661 (and that's SLOW - slower even than waiting for a yard tap to drip!). I have yet to eat there, but I'll report back when I do.
