Mark Wahlberg and one of his sons joined another father and son duo for an early dinner at Katsuya Hollywood on Friday.
"They were all just as nice as they could be," an onlooker tells PEOPLE. "The kids were having a blast hiding underneath the big table in the booth."
The group ordered several of the restaurant's signature dishes including creamy rock shrimp, baked crab hand rolls, Yellowtail sashimi with jalapeno and more.
Wahlberg – who will star in Transformers 4 – and crew also enjoyed a special lobster dish created by the chef.
