King Street Blues is great for kids, if you're looking for something casual, but not cookie-cutter. The Majestic is also relatively kid friendly. We take our kid to Murphy's for lunch and early dinners (it gets a little rowdy later). Austin Grill is a kid favorite. If your kid is relatively well-behaved, The Warehouse or Landini Brothers is good if you're looking for something a little fancier. In fact, my dc is very good at restaurants, so there's only a handful that I wouldn't take him to (Restaurant Eve, for example). We took him to Jackson 20, and it was fine.
