On its social media accounts, IHOP has announced that it will be “flipping” its name to “IHOb” on June 11. On Monday, the restaurant chain — whose full name is the International House of Pancakes — unveiled a series of cryptic posts encouraging people to guess what the “b” in “IHOb” might stand for. “We’re flippin’ our name to IHOb,” the posts read. “That’s right, with a ‘b.’ Find out what it could b on 6.11.18” It’s unclear whether the move will lead to an actual name change for the restaurant or if it’s just part of a new marketing campaign. A spokesperson for the restaurant declined to share any information about the social media posts. IHOP is owned by Glendale-based parent company Dine Brands Global Inc. Shares of Dine Brands rose 53 cents, or nearly 1 percent, on Tuesday to close at $63.04 on the New York Stock Exchange.
