I am going to compile a list of places in Orange County, California where kids eat free with a paid adult meal. Eventually I may expand it to include southern LA county, western San Bernardino and Riverside counties, and northern San Diego county.
The list so far (very short):
Chik-Fil-A (all OC Locations)- Tuesdays 5:00-8:00 PM
Super Mex (Irvine Location) - Thursdays
