If I'm eating at QS I'm eating a kid's meal always. It's not about saving money for me, it's because the adult portions are just too big. I rarely snack between meals but I've found the kid's meals more than enough for me and I usually get the cutie as a side and eat it later on.
I'm a fan of the breakfast bowls and the grilled cheese at Woody's Lunchbox at HS. More than enough food on either one of them. I like the bowls at Peco's Bills at MK. While not a kid's meal I usually get the chicken fried rice at Yak and Yeti in AK. I think it's listed as a side but it works as a meal for me, I always carry a bottle of water with me so I don't even need to get a drink. I tend to be at the parks during a festival at Epcot so I usually just eat around the booths. I do enjoy both QS places in France for breakfast but those aren't kid's meals. Every once in a blue moon I'll get a kid's meal from Mexico.
If I'm not at Dolphin, I'll get the kid's version of the bounty platter for breakfast at the resorts. Scrambled eggs, bacon and for a drink I'll get an orange juice.
