Hands down best ethnic food I've tasted is Persian food made by people who emigrated from Iran. If I'm in a city where they have good Persian (NYC, LA/Orange Co), I'm finding it.
Used to work for a Persian fella. He’d take us out to a Persian restaurant in Atlanta on occasion. He’d babble something in Farsi to the owner, we’d get set up at a private table, and they’d just start bringing dishes out.
Could of been a stewed camel for all I know, but it was damn good.
