We ate there in May 2007, obviously on the 2007 DDP, and we loved it. It was the best meal we've ever had at Disney, and we thought it was well worth 2 TS credits under the old plan, which included both appetizer and tip.
I doubt that we would use DDP for CG under the 2008 plan, because CG is one of the restaurants where the changes really hurt you big-time.
At many restaurants, the loss of the appetizer is no big deal to us, but at CG the appetizers are an important part of the meal. Two TS credits for a CG meal that doesn't include one of their outstanding appetizers is a rip-off, IMHO.
I'd rather eat at one of the fine-dining restaurants offsite and pay more realistic prices out of pocket.
