The 2 go-to's I would recommend for kids are Crystal Palace for b'fast (Winnie the Pooh characters) IMHO, b'fast there is MUCH better than dinner (I LOVE Pooh's puffed french toast) and for dinner, I would suggest Chef Mickey's...the food at CM is good, kinda like a WDW version of Golden Corral, but it also has all the main characters at once...if it's your kids first visit to WDW, they will LOVE it!! Just a note, that it's kids, (LOTS of them) and it's noisy and could be crazy at times, but again, the kids will love it! I would check the other buffets for their menus and characters...hope this helps!
