I used to work in a pizza place that had an asshole owner who thought he was a genius. He'd opened a pizza and Chinese place. He called it (I shit you not) *Won Ton Parmesan*. It was closed 4 months later. He couldn't figure out why. I told him nobody wants to eat Italian made by Chinese and nobody wants to eat Chinese made by Italians. There are lines that shouldn't be crossed and a lot of questions to answer. He was using Italian ingredients in the Asian stuff and vice versa. He was such a cheapskate he'd found ways to cut corners on both sides of the menu.
Still, he refused to understand that by mixing them, you cheapened both. But his insistence was that he was a genius and should have got rich. I asked if he'd let his granddaughter (he was proudly Italian) marry a Chinese guy, he nearly had a stroke. He still did not see how keeping these things separate made them better.
Even if lets say the original cooks bring something magical to the table and you just need them. How many ethnic restaurants are there in a country? 1000? 10.000? 100.000?
Ok then bring 100.000 chefs, you dont need the rest of staff to be ethnic. So you dont need 2 million ethnics, just 100k
White people are the best at making any kind of food, if it's being served to other Whites. Because Whites understand our own palate best, so we can make food that White people will like. It might not be "authentic" but we'll enjoy it more. The same can be said for any race, respectively.
Pizza in Japan is [fuckin' rank](https://japantoday.com/category/features/food/domino%E2%80%99s-japan-apologizes-for-fish-and-chips-pizza-%27that-insults-both-england-and-italy%27-with-free-pizza-offer). I know that example is just dominoes but it's all like that, they put the grossest shit you can think of on it.
