Artist Point and Yachtsman Steakhouse are amazing . We tried both places on our last trip and both were so good that they are definitely on our list for next time .
The best steaks I had last month were the Filet with mushroom risotto at Le Cellier (1 credit on the DDP) and the Filet at Narcoossee's (2 credits). Both were tender, flavorful and perfectly prepared.
Shula's at the dolphin is not included on the DDP, but that is the BEST place to get a steak on property. Everything is ala carte and the sides are huge. A salad usually serves two and each side usually does the same. When you first arrive they will wheel out a cart with all of the meat and explain each of the cuts. I know you are on the DDP, but this is worth going off the plan, maybe use a 2 credit dinner and then pay out of pocket to go to Shulas.
