We were there for dinner in Oct. We had the dining plan but opted to pay cash for the dinner. That was a good decision as we did not feel that the meal was worth 2 credits. We ate our usual filet, my husband had it with risotto and I requested the potato side dish (I think they were mashed). The steaks were at least as good as they had been on previous trips (delicious). I just couldn't see using 2 credits for a $43 entree meal. Our 11 yr old ordered a side dish as his entree. It would have been an extreme waste of credits to use 2 for his dinner so we felt the side dish was a good option for him. We skipped dessert.
The food was, as I said, very good. We don't typically eat at the signature restaurants b/c we use the regular dining plan. Looking at the menu prices, I don't think it is usually a good value to use dining credits for signature meals. If we used the deluxe dining plan, that would be a different story.
