Chris Pratt and Son Have Dinner Date with GF Katherine Schwarzenegger

Chris Pratt isn't slow-playing the whole "meet my girlfriend" thing with his kid -- 'cause the trio was looking like a picture-perfect fam Wednesday in Malibu.

The "Jurassic World" star was with his son, Jack, and his new boo, Katherine Schwarzenegger, for a dinner date at Soho House. The good news for Chris ... Kat and Jack seem to be getting very familiar with each other.

Remember, they all just went to church together Sunday and afterward grabbed some sweet treats ... for Jack and Chris.

Can't blame Chris for moving things along at a brisk pace -- Anna's definitely done the same with her BF in the time since she and CP filed for divorce.
