Now through September 25, 2016, kids eat free at IHOP with the purchase of each adult entree from 4-10pm at participating locations. However the geniuses behind what I have to assume is at least a million dollar campaign forgot one key detail during all their meetings. I couldn't find a list of participating locations on their site.
That being said, you'll probably want to call your nearest IHOP before heading off with the little ones in toe.
