Donald Sterling has NO shame over his racist rant ... he hit the town Wednesday night at a high-profile, celebrity-packed Beverly Hills restaurant.
Sterling didn't want to talk to our photog about the Clipper fallout and his lifetime ban ... but he seemed more than happy to mingle inside The Grill -- one of the most popular entertainment industry hangouts in all of Hollywood.
Here's what's breathtaking ... Hollywood is liberal. Liberals are indignant over what Sterling said. And, the tables are all close together, so smack talk can be easily heard. Yet there was Sterling, right in the thick of things.
He needs to read "Kitchen Confidential."
