The following information have been officially confirmed and given by Euro Disney SCA, the company running Disneyland Paris.
A new themed area will open at the Walt Disney Studios Park on July 15, 2014. Named La Place de Remy, it will be a subsection of Toon Studio.
La Place de Rémy will contain Ratatouille : L'Aventure Totalement Toquee de Remy (the ride) but also a restaurant, officially named Bistrot chez Remy plus a shop (Chez Marianne Souvenirs de Paris). But the shop will open later, in Fall 2014.
The ride will take place at Gusteau's restaurant, from Paris' roofs to the busy kitchen, through a cold room and the restaurant's room watched by the fearsome chef Skinner... the adventure is going to be lively and tasty!
Bistrot chez Remy will be visible from the ride itself, just like the Blue Lagoon Restaurant from Pirates of the Caribbean... It's going to be a great restaurant with qualitative French cuisine!
