"Black" Church's are the same as any other church.
The Church (you and me) are multi-ethnic as well, so just give it a shot, if you have a problem going to a single ethic church (that is not your ethicnicity ) just give it a try.
I used to go an all Latino (Read:Mexican) church when I was little and boy do they take worship seriusly and the food was incredible.
Oh and for your question....
Revelanthas a pretty cool church directory to find a church in your area.
