Remember these are my opinions

.....
Can't stand Coral Reef....yuk to both the food and service. If looking for good seafood and service, go the the Flying Fish or even Kona. We would NEVER eat here.
Tutto Italia is good but very expensive unless you are on the
DDP.
Teppan Edo is ok, but come on its just habachi people, and I'm sure we have all had better habachi at our local Japanese restaurants at home. I know of 2 or 3 that surpass in both quality of food, service and show around my home. I would not waste my time or dining credits here when there are so many other places to enjoy while at WDW
Tokyo Dining is pretty good. We enjoyed our view and the calmer atmosphere while dining. The green tea pudding is fantastic.
Chefs du France is ok, not great and the service is spotty.
Rose & Crown is mediocre. It does however have a great view for Illuminations.
China - I haven't tried since refurb, but I hear its much better and probably worth a visit in the future. But I have to keep in mind again, its Chinese food and I can probably find better around home or at PF Changs.
Biergarten, we love this place!

Now the food is your typical German fare, but it is consistently good. I am not always a big fan of buffets, but we like this one for the different options available. But the real winner is the show and the beer. We so love to watch the show while we dine. And if you have kids in your party, they love to join in the fun which makes for a special dining experience for everyone.
San Angel and Marrakesh we have never been to. I would like to try them some day.
