IHOP (Internation House of Pancakes) didn't have a gluten free menu on their website. They didn't seem to quick to offer any options in their email either.

Thank you for your inquiry about nutritional information. Our restaurants located in communities that have legislated disclosure requirement are complying with those regulations. We are currently working on our plan to provide all guests with more information on the nutritional values of our meals and expect to have updates available later this year.
We appreciate your patience and thank you for your inquiry.
