It would be no small task to call everywhere asking about kid-friendly promotions, thankfully the diligent penny pinchers at FrugalLiving have compiled a huge list of specials.
The list is arranged by the days of the week, with a link to the restaurant and additional notes about the nature of the promotion. Where available there is also a link to the kids' menu so you can taken a peek at the food ahead of time. They have done an excellent job cross referencing the list, if a restaurant you're looking at has multiple promotion days throughout the week the entry for any given day will note the other days.
