Crazy scene on the streets of Atlanta … a bunch of men got into a huge fight in full view of security guards … and it’s all on video.

Ya gotta see the footage … it’s complete chaos outside a business as a well-dressed group of guys brawl … fists and feet are flying and whizzing all over the place.

Sources tell TMZ … the fight happened outside The Interlock in Atlanta a little after 11 PM Sunday night … with security breaking up the fight.

We’ve seen lots of fights at the Atlanta airport over the years … but now things are spilling into the streets.
