Thing with Sam and his family may be that families (apart from occasional visits or official business like with Spock's parents) are not normally allowed on starships until TNG's era.
As for the more casual (but important) conversation while eating, I think we had a fair amount of that in TOS with Kirk and McCoy in particular, and sometimes in TNG and it's spinoffs with Ten Forward/Quark's Bar/Neelix's kitchen etc. pretty sure Archer or Tucker sometimes cooked up some Earth things on occasion too.
