Eating meals together while looking at each other triggers the release of oxytocin and dopamine.
"We're habituated, for example, to eat around a campfire looking at each other. And we get tremendous pleasure from that. We get oxytocin from that. We get dopamine from actually doing that." (said at 0:15:51)
While neurobiological literature indicates that ingestive behavior (food reward) engages the mesolimbic dopamine system and social bonding/interaction engages oxytocin signaling, the specific assertion that eating together while looking at each other directly releases oxytocin and dopamine is a conceptual extrapolation rather than an empirically measured biomarker trial in communal dining settings. Preclinical models and theoretical reviews describe overlapping oxytocinergic and dopaminergic mechanisms regulating both ingestive behavior and social context, such as oxytocin signaling mediating the social facilitation of eating in rodents.

"Collectively, the results of the current study identify endogenous HPCd OT signaling as a novel substrate in which OT synergistically influences eating and social behaviors, including the social facilitation of eating and the social transmission of food preference."

"We highlight interactions between OXT and the hypothalamic melanocortin system and mesolimbic dopamine system as potential mechanisms for context-dependent behavioral selection. Finally, we suggest that OXT effects on behavior result at least in part from a positive shift in reward value of the stimuli that will fulfill the strongest homeostatic need at the time."
