The Caucasians sitting and eating there sure are risk takers. Avoid ferals at all costs.
It all depends on the place. My wife and I have eaten at some black eateries. Some of the best ribs or fried chicken you can get anywhere. But watch your surroundings! Had some good stuff in Kansas City, MO while visiting there. We're from the West Coast, and took a chance looking for places to eat. As long as there are a few other white faces around it's okay.
