It’s been more than a week since IHOP teased the public about its name change to IHOb — and while lots of people are talking about the pancake joint, the publicity stunt has not resulted in more diners in its 1,750 eateries, according to research.

But the chain’s “word of mouth” score as of June 18 is its highest since 2012 when YouGov began tracking the franchise.
