The World of Refreshment was a Nuka-Cola manufacturing plant with a guided tour, featured in park advertisements. Before Nuka-Cola Quantum was released, the water was tinted a blue color to simulate the look of the beverage, but now contains the drink itself. The river is infested with nukalurks.
Accessible through the southern side of the structure, just beyond the river of Quantum. Just left of the building's sign is an enter sign with an arrow. Following it will lead to the entrance of the building. Upon entering, one will be in the newest feature, the World of Refreshment Tour that highlights the history of Nuka-Cola Corporation while following the river.
Hidden Cappy clue - In the western town section of the Quantum River tour, on the left side of the river directly across from a large Nuka WILD sign on a blue building with a western female model, will be located on the right side of said building.
Nuka T-51 power armor - Behind a sealed door next to the Tunnel of Love. The door is unlocked by an Expert locked terminal in the upper area. It can be reached by proceeding eastward from the armor, entering the hole in the right wall and going up the stairs. If needed, the password to the terminal is located on the roof by a Nukalurk king, a mattress, and two weapon workbenches.
Ice cold Nuka-Cola Orange - Behind the first billboard on the right, upon entering from the exit or end of the Quantum River tour. It is at eye level, sitting on a beam alongside a Nuka-Cola Grape.
