Joined by four other friends, Fox, who wore a distressed, cropped T-shirt over black jeans with pumps, and Arnett “seemed very engrossed in their conversation, which seemed to be a mix of both business and pleasure,” an onlooker tells PEOPLE.
Fox and Arnett – who costar in the upcoming Teenage Mutant Ninja Turtles movie – indulged in tuna and lobster tacos, New York pretzels, brick-pressed chicken and burgers.
For dessert, the table ordered up bread pudding, pot de créme, doughnuts and strawberry shortcake.
