We enjoy many different restaurants at Disney and use the TIW card not a dining plan for our TS meals. We try to plan different types of cuisine every day if we can. We have always enjoyed BOG - dinners more so than lunch. The French Onion soup is fantastic as are several of the entrees. We also really enjoyed Via Napoli, Les Chefs de France and Le Cellier at Epcot although Le Cellier is quite pricey. But the food there is outstanding. We also enjoyed Teppan Edo (but Teppan Edo is pricier like Le Cellier) and of course they're all very different types of food so you have to decide what you like most. We liked La Hacienda too but they stopped taking the TIW card so we don't go there any more. We recently decided that Disney has gone overboard on their buffet prices so aren't doing as many of those any more - but that said our absolute favorite is BOMA at the AK lodge. Always delicious and a culinary treat - and it has a lot more variety than found at either Sanaa or Jiko. We're trying O'Hana for the 2nd time on our next trip as it's been awhile since we went there. We need a refresher on that one to see if the food is really "all that". At HS we would choose either Mama Melrose or 50's Prime Time cafe over Sci Fi Dine-In. We went to Sci-Fi last summer for the first time and were NOT impressed AT ALL with the food there. It's a cute theme - but so is 50's Prime Time. The food was noticeably lacking at Sci-Fi for the price. 50's is American comfort food & Mama's is Italian. At AK park we also really like Yak & Yeti although they don't take our TIW card. Tusker House is good too but the Yak & Yeti TS restaurant is excellent. Afraid we haven't experimented much with TS at Disney Springs or many of the other hotel properties…trying Turf Club for the 1st time at SSR on our next trip too. At MK we would choose either Liberty Tree Tavern or Tony's Town Square (but we like the lunch menu there). We've had positive experiences at both of those and we always slip in a cheap meal at The Plaza too.
Have fun planning!!
