You can't always take out soup and pretzel bread from Le Cellier, they apparently do this on a case by case basis. You can ask, but be prepared to be told "no." As for
DDP, not sure about that one because I don't know about spending a full TS credit just for some soup and pretzel bread, and they won't accept CS credits.
Disney TS restaurants are not set up to accept carryout orders, and most will not.
