The Cafeteria is a huge, indirectly-franchise-based room on the fifth floor. It has movement detecting lights, so by default, the room is pretty dark. The tables are pretty dull, too... that's odd.
When a character sits down at a table, the table's theme will change from dull to match with the franchise of who sat down(e.g. Cuddles Pinkercat would cause the theme to become Team Three Star based).
Depending on the desired dish, it will appear on the table like magic.
