Writers rooms may vary in terms of the decor or the available food (“Everybody Loves Raymond” was always the champ in that regard), but the basic atmosphere is the same from room to room, show to show. You will have a large space (in this case the common room of a suite of offices), usually around a table (here a big coffee table) where the writers can gather to eat, to brainstorm and to argue about completely unrelated matters, which sometimes end up fueling stories and other times are just procrastination while everyone waits for the next good idea.
