The real question is how will they behave, will they sit quietly for over an hour? Age doesn't matter it is their behavior. Another question if they misbehave are you willing to leave or have 1 of you take the kids and the other stay and eat. How do they do now when you go out. Meals at Disney take a long time. And yes they have to behave, people are paying a lot of money for a nice meal they don't want fussing kids at the next table.
Personally I would wait till they are older and chock it up to having 3 kids close and young and one of the things I have to look forward to when they are older.
Well put. IMHO it would be VERY stressful bringing three kids those ages to a nicer restaurant where they will ahve to be quiet and sit still for 90 minutes or longer. And when you're stressed, you won't enjoy the meal.
I would either get a sitter or wait until they are older. If you do decide to go, book when they first open at 6:00pm, get there to check in ten minutes early, tell your server to keep things moving and eat fast, and be very prepared to have it all wrapped and have to leave--fast. And that means one parent taking the kids out of there while the other parent settles up.
Also there is a dress code.
I just booked all of my sister and BIL's ADR's for an upcoming trip. Three years ago when they had kids 7, 4 and 14 months, we ate at a lot of sugnature places. But there were four adults to wrangle three kids, and I left one of the meals with the 14 month old because she was getting tired and cranky, and no way we were going to subject the restaurant to that.
This time, they've got a 10, 7, 4, and 18 month old, and we decided it was just too much, so I booked a lot of moderate places, and one night DH and I will take the kids "someplace" while my sister and her DH go eat at Citrico's.
For good food that's not character dining and is family friendly, try the Kona Cafe, Yacht Club Galley, Chef's de France, 50's Prime Time, and Mama Melroses.
