Our family was at WDW at the beginning of October and as part of our tour of DVC, we got four free dinners. Our guide told us that the Pepper Market was one of the better choices in terms of getting the most for our free meal. We went and were somewhat disappointed. The big problem was in how slow our server was -- I think we waited 15 minutes before we could even go up and get our food. Our daughter (4 YO) ordered pizza and it was quite nasty. The adult food was pretty good, but don't go there if you don't have time to spare. The food stations can be very slow... even simple things like the bakery/dessert table.
As someone else said, it was passable for a free meal, but I wouldn't go out of my way to eat there.
