The immigrant melting pot, and the food that results is American food culture, at least when you're outside of homogeneous strip malls that the Midwest is famous for. So in Southern California, there's no shortage of immigrants who started their own restaurant or food truck. Next to the 99 Ranch or H-mart, there's little boutiques of food from back home. And then to top it off, there are fusion places targeting the American palate, which just couldn't exist anywhere else in the world.

If you think American cuisine consists of massive chains; TGI Fridays, Olive Garden, Red Lobster, Hooters, Texas Roadhouse, etc, then no wonder you don't think highly of American cusine. But if you branch out from there, there's a ton of food culture, and Southern California's a great place to experience it.
