The reunited couple – who are expecting their third child together later this year – dined at Killer Shrimp in L.A. Thursday
While dining at Killer Shrimp restaurant in Marina del Rey without their two sons – Noah, 3, and Bodhi, 2 – Fox and Green were “friendly and chatting with the waitstaff,” says an onlooker.
At lunch, however, Fox, 30, and Green, 43, kept the PDA to a minimum and “were pretty quiet with each other” as they dined on the restaurant’s Killer Shrimp “Original” dish, adds the source.
The actress wore all black and kept her sunglasses on during the meal and was seen fiddling on her phone throughout the low-key meal.
“Brian and Megan are living together in Malibu with their boys,” a source told PEOPLE in June. “They have been getting along and seem very happy. They are just waiting for the baby to arrive. During their separation, Brian always hoped Megan would change her mind about the divorce and he is very happy that she did.”
