I'm being dramatically misrepresented. The OP asked about the value of the DxDP IF you skip some entitlements, so I laid out several scenarios, and the no-app, no-dessert, was 1 of several scenarios I laid out. Here was the relevant part of my answer:
Now, a few general comments. We each come from different dining experience backgrounds. You said that no-app, no dessert and tap-water sounded "grim" to you for fine dining.
First off, you're making the assumption that California Grill is fine dining. What level of dining constitutes "fine dining" varies based on experience. Personally, I believe the only restaurant at Disney that qualifies as "fine dining" is Victoria and Albert's. I eat at restaurants of that quality, 3-4 times a year. At such restaurants, I am likely to order more than just an entree. I've done many multi-course menus at such restaurants, including an upcoming reservation in a couple of weeks for a 12-course meal at a Michelin starred restaurant. Daniel Boloud, Alain Ducasse, Dan Barber, Joel Rubochon -- these are the real purveyors of fine dining. White linen service, formal attire, etc. I'm not criticizing California Grill or the other Disney signature restaurants -- I like them quite a lot, but they aren't fine dining in my book. They are slightly upscale casual dining.
Now when I am eating in a truly fine dining establishment, what do I personally drink? Almost always, wine and/or tap water. I don't want caramel-ish carbonated sweetness ruining the delicate flavors prepared by the chef. And bottled waters are 1 of the great scams of our time. (Blind taste test after blind taste test, demonstrates that tap water performs just as well as bottled water in taste tests). (

So as I said, most "signature" restaurants are what I consider to be high end casual restaurants. Nothing really far out of the box. Good quality ingredients, but not exactly flying in foies gras from Paris. Good service, but not a Tuxedo'ed staff serving on fine China, Crystal and silver.
I eat at these types of restaurants at home, several times per month.
When I go out for sushi, I get a large plate of assorted sushi, just as good if not better than the California Grill. I don't eat appetizers or desserts.
At other similar restaurants, I do typically drink tap water or wine. I may sometimes have a soup or salad appetizer, or my wife and I may split an appetizer.
I do NOT find the desserts at the signature restaurants to be "dainty."
Dainty would be 1 tiny scoop or sorbet.
Most of the desserts at California Grill include some time of pastry, with a sweet sauce, plus ice cream. Such desserts are at least 500 calories, which is a huge portion after already completing a meal that may have been 500-1000 calories. (In an entire day, an adult should consume 2000 calories).
When I go to a casual restaurant at home like California Grill, or Artist's Point, or Narcoose's.... I never get my own dessert. Half the time, I skip dessert entirely, the other half the time, I'll share a dessert with 1-3 more people. (At a recent French American restaurant, we split an amazing dessert 4 ways).
For someone, for whom a restaurant like "California Grill" is special occasion fine dining, I can understand wanting to maximize the experience with as many courses as possible. But for people who eat at restaurants of that quality on a very regular basis, it is indeed overkill to constantly order appetizers and desserts for everyone in the party.
I do use the deluxe dining plan at Disney, if and when it's an upgrade from free dining. Because I do want to eat at signature restaurants almost every day, as it's the level of dining that I'm used to. And I do get enough appetizers, beverages (often coffee) and dessert, to make it worthwhile. But if I did have to pay full price for the deluxe dining plan, it would be a pretty close call in 2012 pricing.
