Richie, 19, and Disick, 34, were out at the star studded restaurant which is a favorite of the Kardashians.
Sofia wore her hair down and sported a white turtleneck with jeans while Disick wore a 'Playboy' hoodie and jeans.
The pair started dating in May following a trip to Cannes and since then they have been photographed in Santa Barbara, Miami, Italy and Mexico also.
Richie seems quite taken with the father-of-three who has endured several issues in recent times.
RadarOnline.com revealed how he was hospitalized earlier this year after a drinking binge.
But insiders claim that Richie has been a steadying influence on him since the pair started seeing one another.
And at least she has the approval of her famous father Lionel Richie whom she claims has been 'supportive' of her relationship with Disick.
