Magic Kingdom dining

I'm stuck on where to eat in Magic Kingdom this fall. Usually when we go we are so focused on rides we just grab snacks around the park throughout the day. However, this time my husband's parents will be coming with us and I'm sure they'll need a break to sit down in some air conditioning. My mother in law is a sucker for good atmosphere but won't eat anything Asian (so no ohana...) We are willing to take the monorail somewhere close by but definitely don't want to spend too much time away from the rides (let me know if this is unrealistic). My kids are 10 and 6, so while characters are fun they're not a priority. If we do character dining they'd prefer princesses to Pooh and Mickey. In fact they probably wouldn't like to see "little kid" characters at all. I've seen very mixed opinions on Be Our Guest, 1900 Park Fare, and Crystal Palace. Based on my criteria where would you go? Also open to options outside of these three listed. Thanks so much!
