It has two entrances: a front door and a drive-thru window. The interior is divided into three different rooms, the front room, the back room, and a secret room. The front features two self-serve kiosks, a digital menu on the front wall, a Cluckdonalds logo, and a front counter with various items that can be interacted with and a menu directly behind it.
The back room hosts a set of shelves filled with books and other paraphernalia. A keyhole in a book is also located here that, when unlocked with the Golden Key, grants access to a back room that houses the Death Ray.
The secret room features a desk with the Death Ray in a glass case and the Cluckdonalds logo with red glowing eyes behind it.
The front room features three cash registers that can be interacted with by players and a tip jar which grants 250 - 750 when broken. In the back room, there is a set of shelves with a safe that can be broken for 1,000.
