A red curved line under the last two letters of this diner chain turns them into a smiley face. What is the name of this restaurant that serves breakfast all-day and is known for their pancakes?

International House of Pancakes, otherwise known as IHOP, opened its first location in California in 1958. A red curve under the "OP" in "IHOP" is meant to turn the letters into eyes and the red curve into a smile.
