The Schwarzeneggers got the fam back together Monday night for some fine dining at celebrity favorite sushi spot ... Nobu!
Check out the pics ... it was a whole family reunion with Arnold and his ex-wife Maria Shriver ... plus all of their kiddos -- Patrick Schwarzenegger and his wife Abby Champion, Katherine Schwarzenegger and her hubby Chris Pratt, Christopher Schwarzenegger and Christina Schwarzenegger.
The bunch appeared in great spirits after a successful family outing -- which, as you can see, didn't include any grandkids.
