Nine Dragons- never tried it.
Liberty Tree Tavern- It's okay. I haven't been in a while, and there really is no great choice in MK, so as far as MK goes, it's as goodas anything really.
Akhershus Storybook Princess Norway- never tried it. The menu and CC deposit are my concerns. I'm not that hot onthe menu.
Les Chefs at France- pretty good. The green beans are very good. AS is typical of French food, the desserts are a true highlight of the meal.
'Ohana- I really like this place. Expect LOTS of meat! Nice inthat it comes wil salad and VEGGIES. If you aren't huge eaters, consider asking for half portions. We always end up throwing food away.
Yak & Yeti- I've only done the quick serve side, which is among the best in AK. AK is also a little lacking in dining choices.
Crystal Palace- As I said, MK is lacking. This is probably the best choice in MK, but it's not fantastic. It's one of the better character meals offered.
Mama Melrose's- I haven't been in quite a few years, but this was among our worst dining experiences anywhere. I have read many positive reviews since, but it IS one of few Italian places on property. It wasn't the food that was bad, it was the service!
LeCellier- a great place.
There arenot MUST do's when it comes to WDW dining. You can't dine everywhere on any given trip. The best, I say is always to mix it up. The only must I woudl say, is maybe your home resort (See below).
One thing I notice is that nearly all of your ADR's are in the parks. Much of the best dining is at the various resorts. Resort dining also gives you some flexibilty, as any resort can be paired with any park. You also don't say where you are staying. If you are staying at a deluxe, I would strongly encourage dining at your home resort, or near your home resort, depending on where it is.
If I was going to change anything, I'd sub a dinner inthe BWK/BC/YC area for Mama Melrose.
A Signature dinner works well if you think you won't take advantage of your arrival and departure day dining.
Another way to cover it with
DDP credits, you can pay for ONE inexpensive TS meal along the way with cash: say one person uses DDP credits for the meal and one peson gets an inexpensive entree and you share...then another night, you reverse. OR one person gets an expensive meal at the signature dining, and one person gets a less expensive entree, and you use the DDP to pay for only one person's dinner. You can easily make the swap work at some of the a la carte type menu places. Take Mama Melrose; one person might just FEEL like having a pizza that night. Or maybe just a salad. On DDP, I typically reach apoint during the trip where I feel like I've had one too many desserts. Also higher priced entrees tend to be steak and seafood....for me, I periodically PREFER one of the inexpensive entrees.
