As someone who was a former CM at Artist's... if you're not spending time at the main pool that day, skip it for lunch. The sandwiches are decent, but you can get better at Earl of Sandwich. The flatbreads leave something to be desired and the chicken tenders are the same ones you'll get anywhere on property. The chips are good, but not worth the headache imho. Also having to share the cash registers with the gift shop. The single most annoying thing ever. (Keep in mind, I have not worked there since Aug 2011, and have not eaten there since May 2015. So if things have changed since then, please disregard).
What I will suggest you try AP for is breakfast. Yes, it's standard. But they do provide easels for your kids to color on. And, (keep in mind that I'm going off 3.5 year old into here) if your child asks, they'll even hang their drawings on the wall. It was actually one of my favorite things to do as a CM. It absolutely makes kids days to know that their work is on display for every single guest as nd CM to admire.
