I love the Bay Area, but suburbs are suburbs.
Edit: I checked; it's not quite the closest "fine dining", but there actually is one a short walk away =)
The Bay Area isn't uniquely bad. It just isn't uniquely great either. It's a nice place to live. So are lots of other places. There are some great restaurants. There are some great restaurants in other suburbs, too.
To answer your question- people of color would be treated identically to white people. You do realize the racial history of the midwest is safehouses for the underground railroad and soldiers for the Union army during the civil war right? And that Iowa legalized gay marriage years before California.
There are good and bad people everywhere, smart and dumb people everywhere. Negative stereotypes based on city, state or region are just as bigoted as any other stereotypes.
California, on the other hand, elected Ronald Reagan as governor in order to "send the welfare bums back to work" and then re-elected him because they loved that he banned black people from carrying guns.
There is no "gotcha" to life in the Midwest, the cost of everything in coastal cities is just ridiculous. You don't have to be surrounded by luddites and people who hate minorities to buy a house for less than $2.6 million.
BRB, going to meet a friend for lunch at Chili's.
