This description from the Disneyland Paris website explains briefly the theming of the Pizza Outpost:
This is where chattering parrots invite you to pick your favourite dishes: pizzas, lasagnes, pastas, salads... Intrepid explorers of all ages meet to tell their tales in this restaurant, on the edge of the tropical forest, relaxing in front of the stone fireplace or enjoying the view from the veranda.
There is beautiful decoration throughout this restaurant, with so many things to see and do! The main dining area houses a massive tree where there are animatronic birds surrounding you. Not unlike Walt's original idea for the Enchanted Tiki Room.
Let's take some time to have a look at some of the hidden treasures.
