OK, I perused the menus to see, where would I take
my kid?

My youngest is almost 16 now, but the older boys have girlfriends, so I could have DGK's to take in a few years!
MK -- CS looks pretty lame, even for adults.
Casey's Corner: has no kids' menu, kids have same options as adults.
El Pirata y el Perico: taco, cookie, and beverage
Main St Bakery: doesn't look like there's a kid' menu, so same options as adults.
AK -- CS not great options for kids
Flame Tree: chicken wings or hot dog (may be ok)
Tusker House: mac and cheese or chicken drumstick (may be ok)
Pizzafari: cheese quesadilla may be ok, but really dumb there is no pizza for kids!
MGM -- CS options not great for
anybody, but...
Catalina Eddie's: don't see kids' menu? same options as adults?
Toy Story Pizza Planet: no kids' menu, same options as adults
ABC Commissary: gets bad reviews, but kids' meals includes fried fish and vegetable noodle stir fry, specifies fries and soda available on request
Epcot -- some really unique and appetizing-sounding CS options for kids:
Cantina: beef burrito and soft drink
Electric Umbrella: standard chick nuggets and mac & cheese, but also turkey and cheese pinwheels, at least it's something different...soda and fries on request
Fountain View: don't see kid's menu -- same choices as adults?
Sommerfest: don't see kid's menu -- same choices as adults?
Sunshine Seasons: sweet and sour chicken, mac & cheese, mini sub, chicken leg
Yorkshire Fish Shop: don't see kid's menu -- same choices as adults?
Lotus Blossom: egg roll and beef fried rice
Tangierine: burger, pizza, or chicken tenders, all with fries and drink
Yakitori: teriyaki chicken w/veggies, rice, and soft drink
DTD
WPE: chicken fingers, mac & cheese (the GOOD stuff), cheese OR pepperoni pizza
EOS: PB&J, grilled cheese, turkey and swiss, pizza sandwich
Food Quest (in Disney Quest, requires admission): pasta, burger, hot dog
Cooke's: fish, battered chicken skewer, baby sausages, all with chips (fries)
And those are just CS options at the parks and DTD. I could go through the resort menus as well, but you get the idea. The TS menus are more varied, many with creative desserts, and kids get appetizers as well. Yes, there are definitely some awful and boring options, but it's not all chilled chicken and sugar-free Jello. It may take a little bit of research, but there definitely
are places that will give your kids better variety and more appealing and interesting choices.
