You're walking into a beautiful longue, "Mostro Lounge." It's owned and run by the housewarden of Octavinelle, Azul Ashengrotto. You can see the Octavinelle students carrying trays of food and drinks around, along with the Tweels working at the bar.

"Welcome, dear costumer. Table for one?" He asked; "he" as in Mr. Ashengrotto himself. Your parents would always tell you, "Speak of the devil and he doth appear"... Seems it was true for this case.
