Apparently you have children, so I would suggest doing character meals. We found eating at character meals freed up our park time standing in line for autographs, plus the time and interaction between your child and the character during the meals just isn't possible in the parks. That being said... We like LTT and CP in the MK. O'Hanas @ the Poly, 1900 Park Fare @ the GF,and GG @ the Land @ Epcot.
If you want to steer clear of the character meals and still have a "fun" meal, try 50's Prime Time or Sci-Fi @ MGM or Whispering Canyon @ WL. These 3 are FUN but definately NOT a quiet, relaxing meal.
I hope this is the kind of info you were looking for. Have a great vacation!!
