Well it is called different things.
What do you mean? As far as role-playing perspective it does make sense. Here in the good ol' Midwest we many times have fancy restaurants on the ground floor and a bar upstairs or downstairs for the peasants who are looking for a different type of fun. I prefer the bars to be all honest
I guess I don't know what you mean otherwise
I have one restaurant in the middle of the street in Sanctuary with alot of stools and tables, I have also one restaurant inside one of the premade houses. They gather around the restaurant, but random. They seems talk to each other, but no one listen. You cannot force restaurants staying open, because at 11:30 pm or so, they split and go to bed. Grouping doesn't work, they just move stools from one to other one, random. I was testing Strong, he annoyed no one even he want to smash everything
