Not a big favorite of mine but Murphys is kid friendly and has a couple of good lunch salads. You can always go to Southside, they are very kid friendly and have a few healthier options. Hey, there's always Friendlys!
There is a Penera Bread in the triangle shopping center, also just outside the shopping center is a Friendlys. I'm not so sure on the healthy part, but it is very kid friendly
