In the rest room on the 2nd floor, there is a toaster with the words "Capitoast", if you poke it, you will receive toast with the Capitão logo.

If you go to the service staircase, you have a drink dispenser, if you look closely, it says "SODA" on the first button. (Other machines don't have this button.) Just pull it to get "Montagne Doux" cans.
This is a joke about Montain Dew, which in French is pronounced more like Montagne Doux.

In the exhibition hall, there are displays with books, one of the books is called "Livres des merveilles du monde".

On these same drink machines, there is a QR CODE that you can scan. (The QR CODE is found on all machines.) If you ever scan this QR CODE, it takes you to a "Rainbow 6" search page.

Ubisoft forget to replace this text...

• Poésie Française
  
• Voltaire
