Since you are going in a couple weeks and have yet to make reservations for sit down restaurants, you may have a hard time getting a few.
So I would say you should look on the site here at the menus (under dining - they have a complete list) and get an idea of the places you would like to go to.
WDW has so many places to fit every taste so I can only offer the ones I like, but if my choices aren't your tastes, be sure you can find something that is.
Our favorites include: Ohana at the Poly resort. Oh this is such a good meal. All you can eat family style dinner (yes we do to dinners). It has meat skewers of sirlion, chicken, pork and peel and eat shrimp. Lomein noodles, sticky wings with 3 sauces, a veggie dish with brocolli, snowpeas and carrots.
And dessert....oh the best bread pudding with bananas foster caramel sauce with vanilla ice cream....ugh just heaven.
This is a very hot ressie though, so it may not be available.
Whispering Canyon is another favorite, Crystal Palace is a character buffet in MK that we love.
So those are a few of ours. Good luck and enjoy your trip!!
