Hey, racists gotta eat too ... which is why Donald Sterling hit up an In-N-Out burger joint in Westwood, CA this weekend ... with a pretty young Asian lady in tow.
Our burger spies tell us ... Sterling rolled up to the restaurant (right near UCLA) around 3pm on Sunday in his pimped out Rolls Royce Phantom ... not exactly incognito.
We're told Sterling -- along with the young woman and a man who appeared to be a manager -- walked inside ... and sat down together ... with Sterling only ordering a drink.
Our source said at least one person asked Donald for a picture -- and Donald seemed like he was down -- but Donald's "manager" stepped in and nixed the shot.
The whole group was only in the restaurant for around 20 minutes before they went back to the car and left.
No burger. No fries.
He really is a horrible person.
