Just putting my two cents in- when I heard "lobster section" I thought of it as just a name. Like the "living room" or the name of the restaurant, or like sometimes in parking garages they'll give an animal or a state or something to each level, just to make it more memorable. That's how I thought of it. Like a category, a name to refer to the room.  Also for some reason I thought of it being really fancy, which was why one of the friends was nervous to go there
that's the most logical thing i've heard all week
