As with any of these generalizations, there are outliers. If in conversations about Italian foods, someone brings up the Olive Garden, then I have to laugh, as it is the worst food you could serve me. Chinese food... I've been to Korea, and what we have in the US is American Chinese lookalikes. I imagine Italians laugh at the Olive Garden, and the Chinese laugh at any US Chinese places.
French, we have several places in B'ham that serves French foods, but they are owned by Greeks, ha ha. Even the best Barbeque here is made by Greeks. when people come to visit, I take them to the Bright Star, the oldest restaurant in Alabama, and very classy place, and they serve Southern cuisine, but it is Greek, and was the first Greek Restaurant. It will make you slap your mama. Soooooo good. The Greek Orthodox Church in downtown B'ham has a Greek food festival every year. It is the one time I can actually get those Greek families rendition of actual Greek dishes... the entire city turns out for it, and WOW, brother that food is awesome. Funny though, none of their restaurants seem to serve Greek food, just their "take" on other genres, but they do an awesome job of it. It is actually a local phenomena. Why the hell did a Greek family entrench themselves in Southern Culture going back to the Civil War? But, I am glad they did.
