Okay...I"m going to try and make this as non confusing as possible haha...
So
Breakfast really depends on how into the characters you are. We ate at Chef Mickey's in 06, no kids in the party, just three young adults having some fun. It was too LOUD, and to me it seemed cheesey compared to CRT. Personally unless i was staying at the Contemporary(or had very small children), I wouldn't do it again. The food was standard, eggs, bacon, what have you. Definitely not worth getting up at the crack for unless the little ones beg. If you want a great character breakfast and get lucky Cindy's is really cool. I just love the atmosphere and it gets you into the MK early so you dont have to stand in the throngs of people at gate opening. People young and old will like it there.
I'd say out of all your breakfast options...if you do like characters, would be 1900 park fare. They have unique characters like the Mad Hatter and Alice, who are a trip to watch. Check out you tube and type in Mad Hatter and Alice and you'll see what I mean. If you are not into the characters as much, I'd do Boma(not sure if they have characters here or not). I"ve never eaten here but I"ve heard great things about the food.
Lunch
Coral Reef is all Seafood. Mahi Mahi and stuff like that. So if you guys are big on sea food and like the cool aquarium atmosphere I would pick this for Lunch considering the prices are much lower than dinner. If you can, request a seat near the glass so you can get a cool view of the fish!
Personally, for a lunch choice, I would pick Prime Time just because the food is priced moderately and you get a pretty cool show out of it. The waiters come to your table and act like 'mom' or "dad' and tell you to eat your food and things like that. The only downfall is, sometimes you get a waiter that isn't 'on' so to speak. We got one like the the last time we were there, and it really turned the whole experience into a mediocre diner like lunch. The food was good though, nothing spectacular...chicken and mashed potatoes, things like that.
I"ve eaten in Les Chefs but for Dinner. Keep in mind, World Showcases Lunch prices are much more moderate, but the food choices aren't as good as the dinner choices in my opinion. Our server here was great. I was afraid to try Escargo but he absolutely insisted I would like it, and to my shock and surprise he was right. I ate them all! The lamb was also very good. The atmosphere is a little bit cramped. If you can, try to get a table by the window so you can look out at the lagoon.
I"ve never been to Sci Fi. I"ve heard the food is expensive and not very good though. It's really the atmosphere that you're paying for. I'ts dark and you sit in tables that are shaped like cars while old Movies play on a big screen. It's great for kids, but adults might find it loud and not up to par.
Rose and Crown seems pretty good. I looked at the menu and it appealed to me. It's mostlyi meat and potatoes and of course fish and chips. Children might be bored with the atmohsphere but it sounds just right for your group. Also the prices are pretty decent. I"d pick it.
Biergarten is nice if you like food and a show, and don't mind sharing your table with other people. Think...cruise line, your seated with other random people. The show is pretty cool I dont know how much it's changed since I was young but i remember it was like a Polka themed show, and they did alot of musical numbers with bells. I think your party would enjoy this as well. If you have beer lovers in your party, this is definitely the place for them. They specialize in German beer, and are very informative about the different types and the taste. Reminder, this is all meat and potatoes. Alot of Bratwurst and things like that. Personally i like this food, but for some it could be considered too filling or greasy.
Crystal Palace is the only restuarant that features Pooh and Friends exclusively. I've never actually been inside but i heard it's really nice there. Of course it will be loud, as it caters to the younger crowd, but I've heard good things about the food there. Another restaurant you might not want to over look is the LIberty Tree Tavern in MK, The food there is really good, and they feature mickey minnie pluto and donald.
I can't speak for Tusker House. I"ve never set foot near or, nor read any reviews about it.
Dinner
Dinner is my favorite meal to have in Disney world. The food is always better, the atmosphere is just...magical. I dont know, something about being in Epcot, or MK at night has always given me the chills
OUt of your list, I only really know about the California Grill and Le Cellier. The California Grill is great for dinner if you time it right. From your seat, if you want, you can view Wishes as your eating dinner. They dim the lights, and from what i've heard, its really fantastic. I've been contemplating eating here on several occasions, but I"m an World Showcase fanatic and I always seem to pass it up. For your party though, i think they'd really enjoy this place. It caters more to the adult crowd as there are no characters. But if you do wish to get an ADR for wishes, make sure you specify that with the CM when you call to place the ADR.
I've heard so many great things about Le Cellier I dont know where to start. Although I have yet to eat here, people have told me that they rate it better than any of the steak houses they've ever eaten in. A few years ago i tried to get in for dinner, but they weren't excepting walk ins that night. It's very popular so make sure you get an ADR, but you should absolutely go here. I Guess the cheese soup is supposed to be great. Go there, Go there, Go there is all I can say.
I cant speak for your other restaurant choices unfortunately because I've never been to any of those places. I can however, recommend one of my very favorite resturants which is San Angel Inn in Mexico. The atmosphere alone is worth this dinner ADR. You eat under a blue moonlit sky by the river that El Rio Del Tiempo flows through. Something about that is so magical to me.
Hope my opinion helps, and if not i'm sorry! I hope you have a great vacation!
I need one more dinner though.....
