Brandi Glanville had to be poured into her car after a night out at Craig's.

Brandi was 3 sheets as she left the popular WeHo restaurant Saturday night ... which is what happens after more than 6 cocktails.

She couldn't make it in the SUV without muscle ... not her own.

The good news ... Craig's is pretty expensive, so it seems she's still liquid after getting the ax from "Real Housewives of Beverly Hills."
