I have a question about a lawsuit?

Ok so this past weekend I honestly felt that I was denied entry to a bar because I was black.. Now I have very good reasons to believe this.. I was in down town greenville, nc.. I was with a friend who is Asian.. We went to the first bar and this is what happened he walked in no problem.. When I got to the door the bouncer told me that it is a private party but I was confused because my friend walked right in.. Thinking nothin of it we went some where else.. The next club same thing my friend walked in and as soon as I approached the bouncer he told me that you need a college ID and after that I was furious because neither me or my friend were in college but yet they let him in.. Can I sue them for racism?
