Lisa Vanderpump is trying to make a sexual assault lawsuit go away with money ... problem is, the two sides are a little off -- by around $5 MILLION.
We broke the story ... waitress Karina Bustillos filed suit ... claiming a manager at Vanderpump's restaurant, Villa Blanca tried to kiss her, called her a "c***," and violently grabbed her wrists. Bustillos says she complained to Vanderpump ... who refused to do anything about it.
Bustillos quit ... and filed a $5 million lawsuit for sexual assault and battery.
Vanderpump tells TMZ ... the suit is ridiculous. The woman is an out-of-work actress who has admitted in her deposition she's been fired several times ... once for drinking on the job. And Vanderpump says -- contrary to Bustillos' allegations -- it's already been established Lisa knew nothing about the accusations until the case was filed.
And Vanderpump says the manager in question has NEVER had a complaint filed against him and has worked for her for years. Finally Vanderpump says she fully investigated and there's no evidence the manager did anything wrong.
According to court docs -- obtained by TMZ -- Vanderpump is offering $40,001 -- not exactly the $5 million Bustillos is demanding.
Bustillos has until Monday to accept the offer -- that's when the trial begins.
