I don't know where to find a list, but know the only places I have found that would not accept them is House of Blues, Paradiso 37, and the restaurants at the Swan/Dolphin. I was really surprised to find that T Rex did accept them when we were there this past Feb. In the past I had been refused at Rainforest Cafe, so was surprised they started accepting them. I have used them at just about every restauant in every park (including the ones in Epcot that are not owned by Disney) and other than the Swan/Dolphin all the resort restaurants have accepted them. I go several to WDW several times a year and always use Disney gift cards down there.
