Have often dined communally such as at the Japanese places, Benihana, Shogun, etc. I like that just fine, and realize that when we are just two, we will be seated with others. Usually a fun time.
What I've never been crazy about is the bench seats along the wall system, almost elbow to elbow to the next guy. And one has to stare at the wall the whole time. OK for breakfast, but not for a nice evening meal.
