History
The attraction was revealed as part of internet rumours of an expansion of Walt Disney Studios Park's Toon Studio area. Other rumours about the expansion included a reincarnation of the popular Toy Story Midway Mania attraction to be put in the operating Toy Story Playland. The ride is one of the biggest additions to Disneyland Paris; its show building is similar in height to that of the expansive Pirates of the Caribbean attraction at the neighbouring Disneyland Park, and cost an estimated US$270 million to complete. Following the initial rumours, articles on the Internet surfaced concept paintings, ride blueprints, and images of the first phases of construction, confirming that there would be such an attraction.
The attraction was formally announced in March 2013 at the Euro Disney S.C.A. annual shareholders meeting, with construction completed in June 2014. On 21 June 2014, the attraction was officially inaugurated by president and CEO of The Walt Disney Company, Robert Iger. The attraction fully opened to the public on 10 July 2014.
On 15 July 2017, Disney Parks announced during its D23 Expo presentation that a version of the ride would come to Epcot's France Pavilion at Walt Disney World in Orlando, Florida in 2020. The attraction, along with a new restaurant La Crêperie de Paris, will open on October 1, 2021, on the 50th anniversary of Walt Disney World Resort and the 39th anniversary of Epcot, officially announced on March 9, 2021.
The attraction's exterior is that of Gusteau's restaurant, and the surrounding buildings of the Parisplaza.
After queuing on the rooftops of Paris, guests board their "ratmobiles" and find themselves "shrunk" down to rat size on the roof of Gusteau's restaurant, with Remy and the spirit of Auguste Gusteau trying to decide what meal they shall serve the riders. After deciding on their famous ratatouille dish, Remy and the riders fall through a swinging roof glass-pane, winding up on the restaurant kitchen floor. This starts a chase sequence with Remy leading the riders and other rats away from the cooks, passing through the cold room and under the hot oven.
The little group eventually ends up in the dining area, attracting attention from customers and causing a riot. Chef Skinner tries to get rid of the rats and the guests, while Alfredo Linguini tries to help them escape into a nearby vent. The escape through the vent in the walls is almost wrecked by Skinner, who angrily attempts to grab the rats or the guests through the venting grids. In the end, the little group makes it safely to Remy's kitchen, where the cooking of the Ratatouille is ongoing.
The ride ends at the Bistro Chez Rémy restaurant, where guests are bid farewell by the rat colony and the spirit of Gusteau and invited to join in. At Epcot, the attraction will exit to La Crêperie de Paris restaurant.
Technology
The attraction uses LPS trackless ride technology, similar to Pooh's Hunny Hunt (in Tokyo Disneyland) and Mystic Manor (in Hong Kong Disneyland), which uses rat-shaped vehicles to automatically slide across the ground with no track. It also contains 3D dome segments of the ride that the vehicles ride into.
