We had considered TE in the event we were hungry and around the Fort, as well as out of food in the cabin.
It looks like it's no longer an option.
As for the quality of the food - it has gone way downhill and the drop, IMHO, coincides with the dining plan.
Last year we did the premium package, which, lucky for us, includes everything and all the restaurants except for V&A. We did all the signature restaurants and found a surprise in there.... Citricos. I think it's a hidden gem.
We tried filet mignons in a few of the restaurants - The Yachtman, which used to be outstanding, Narcoosees' and Citricos - the stead was by far the best at Citricos. Plus, it wasn't crowded and the service was very good.
So, if you're interested in a good meal in a quiet setting with good servcie, try Citricos. I know I'll certainly go back.
FWIW - California Grill used to be tops on our list, and last year, we were disappointed with the food and the service. I think they've just become too popular. We were always good for at least 1 meal there, this upcoming trip, we aren't even going to bother.
Quite frankly, we've given up on the restaurants in Disney. They ain't what they used to be.
