If you click on this link and scroll down a bit, http://www.wdwinfo.com/MagicYourWaydining.htm it will take you to a "chart" listing all of the participating Dining Plan places for 2007. The third column lists the 1 Credit Table Services-the fourth column lists the 2 Credit places.
Nope. Most character meals are just one table service meal. I would do as the previous poster said and check out the link provided. You can also go to the www.disneyworld.com website.

You will be directed to a brochure setting out each category (counter service, snacks, table service and signature meals) of meal and where the dining plan can be used.
