According to reports from Club 33 Members, they have been informed that a new high-end restaurant will be opening at 21 Royal Street. The restaurant will have Andrew Sutton as Executive Chef. In addition, the restaurant will serve alcohol. While Club 33 members will receive reservation priority, the restaurant will be open to the public. This marks the first time alcohol will be available to the general public inside Disneyland Park.
More details about the restaurant are expected when it is officially announced to the public.
Update: Disneyland Resort has let us know that there are no new plans for a restaurant. Club 33 members were informed of a new venue that will be available for private parties. The Disneyland Resort would not confirm the location of the new venue.
Update 2: We have also been informed that the private function space at 21 Royal Street will not impact the Dream Suite.
