Our best meal, anywhere ever, was at Victoria & Albert's. This isn't a standard TS or signature and isn't on the DP. Very expensive but it changed the way I cook, or try to, at home.
I enjoyed my food at Narcoossee's and the service was very good. I thought it was crazy loud, though. The Ahi Tuna entree' was delicious. I can't remember what my mom had.
Raglan Road is a favorite of ours. The Appetizer D'Lirrah and entrees (no longer on the menu) have always been tasty, so tasty that we eat too much! DH wants to get the whiskey flight and bread pudding for dinner, if we have time to go back, so that he has room for his dessert
Yak & Yeti was very good. My kids devoured the wok-fried green beans, darn them! They shared the lo mein and loved it. DH and I shared the dim sum and seafood curry. Both were yummy.
We love Via Napoli. DH would be fine with trying something new, even though he's enjoyed the pizza. I've tried and enjoyed pepperoni, piccante, carciofi, and is prosciutto e melone - which is my favorite. It's the only TS that lures me back.
Sanaa was delicious. The bread service is a highlight, but the entrees were tasty.
The Wave is quite good and the atmosphere is very calm, which is a godsend in WDW! I really enjoyed that place and we hope to have lunch or dinner there on our next trip. The breakfast buffet was surprisingly tasty, as I'm not buffet lover, and the kids ate so much that it was hours after we had been on the road home before they thought about food again.
I'm not much of a dessert person, but the PB&J shake at 50's is fantastic. We're going to order one from the bar when we hop over for the evening entertainment.
My favorite QS is Columbia Harbour House in MK. I'm one of the numerous fans of the tuna sandwich, but the fried shrimp my kids ate were quite good.
