You're right that I posted a glowing review of Tiffins. I also commented extensively on price points (and that we did the $28 Taste of Tiffins menu because I wasn't willing to gamble on the costlier options).
In the past you've lamented the degradation of Disney dining, and how things are being "Walmarted" to appeal to the lowest common denominator. The homogenization of menus also bothers me, which is why I'm a fan of restaurants like this (and Skipper Canteen) that are more exotic.
The prices are up there, there's no denying that. Personally, though, I take far greater issue with some crumby burger at Pecos Bill being $16 (yes, really) than food that is actually high quality having (what I think is) standard Disney mark-up. (Actually, for $28, I'd consider several of the Taste of Tiffins options to be good values in real world terms.)
Maybe I'm just another crazy lifestyler, but I realize I'm going to be overpaying for food virtually anywhere at WDW, but my strong preference is in favor of quality, ambitious menus if that is going to be the case. From that perspective, I have a hard time knocking Tiffins. (Maybe that wasn't your intent?)
The same applies with Ample Hills (which I saw you mention previously). The sundaes there are $8.50, but the product is unique and incredibly high quality (particularly the butter cake one). From my perspective, the value proposition is significantly better there than $4.79 hot fudge sundae at Aunt Gravity's. The latter is $4 cheaper, but it's also the same ole generic soft serve sundae you could buy anywhere. The former is a premium product.
Extending the examples further, I think you'd agree that All Star Sports is overpriced at $100/night, but a harbor view room at Hotel MiraCosta is not overpriced at $300/night (even if that is a tough pill to swallow).
I have no issue with Disney (or any company) charging premium prices, so long as they are delivering a premium product.
