Looking at the pictures of the menu boards here: http://www.disneyfoodblog.com/2013/01/15/review-epcots-les-halles-bakery/#more-74438 it looks like a lot of the items are on the DDP. I'm not sure what qualifies as a snack, and what is a CS meal though. I believe if the item is a certain price (maybe $4?) or less, it's a snack. Hope this helps at least a little.
The items with the DDP logo on them are snacks. I will be updating my list with the information from that link.
Snacks can now be over $4. The best way to know is when you see the logo. Check out my list, link below, for more options.
from the above mentioned link.
If youre using the Disney Dining Plan, all but one of the nonalcoholic drinks is available for a Disney Dining Plan snack credit. Its nice to see the continuing trend of $4.00-5.00 items available as snacks.
