Not sure if this would help you, but I just saw Chevy's (Apopka-Vineland Rd) has Kids Eat Free on Tuesdays. We've been there a few times and always liked it.
Also close by is Fuddrucker's- they have the best burgers! If you sign up for their e-club, they send you coupons and special deals. DD just got one for a free kids meal for her birthday.
Sweet Tomatoes is also good, and you can sign up to get email coupons, too.
