Ihop has always served burgers. The "b" is temporary and only to call attention to the new burgers, according to their post.My understanding is that the change is not permanent. It is an advertising ploy to introduce their new line of burgers.
I'm not a IHOP (or IHOb) person, so I'm not familiar with their menu. Have they never served burgers before?
Thought you were very restrained and mature in responding to several posts that did not show the same qualities. Some people should be in counseling.
