They don't really list what isn't included. There are lots of lists for what is included though.
If you're looking to avoid
DDP restaurants, try:
Bistro de Paris is excluded - this is the only park exclusion that I can think of
Victoria & Albert's is only included in the Platinum Touring Package, so not included in the regular Dining Plans
Fulton's
Rainforest Cafe (Both Locations)
T-Rex
Bongo's
House of Blues
Paradiso 37
Everything at the Swan or Dolphin Hotels
I am fairly confident that this is a comprehensive list.
