The most recent Spoodles menu I can find is from December 2006 on AllEars; the one here on the DIS is from November 2006 but looks very similar, with just a couple of minor differences. Is there one newer than December 2006?
If you are looking for ethnic choices for kids, you'll have the best luck in Epcot. I listed some of the TS items earlier in the thread. Some CS meals for kids that look like there is some variety of choices:
MK --
Casey's Corner & Pete's Doggone Good Dogs: 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 --
Flame Tree: chicken wings or hot dog
Tusker House: mac and cheese or chicken drumstick
Pizzafari: cheese quesadilla may be ok, but why is there no pizza for kids?
MGM --
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: grilled chicken and cheese quesadilla, tortilla chips 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. Hey, pizza and burgers in Morocco, yay!
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)
Vegetarian choices for kids are not all that varied. Mac & cheese, cheese pizzas, PB&J, grilled cheese, cheese quesadilla. Lotsa cheese

You could try asking at Yakitori for just veggies with rice, no chicken, ABC Commissary lists a vegetable noodle stir fry, and you could try asking at Pirata y Perico or the Cantina for a bean burrito -- they might have one you could even buy ala carte. Tomorrowland Noodle Terrace has a vegetable tofu noodle bowl, but it's on the adult menu. Buffets for TS will probably give vegetarian kids the most options. I've heard Boma has some good vegetarian options.
