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.
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.
