At least one location has been seen changing signs.
However a reporter did see the following at one location;
Literal signage by the cash register, with the same "IHOb" logo that the chain shared on social media during the week, followed by the words "Burgers Burgers Burgers."
Right next to this sign was another with the classic IHOP logo, declaring "Pancakes Pancakes Pancakes." So this change may not be as dramatic as some have feared.
According to a comment at an unauthorized source it's just a one month promotion.
