What is the nickname of the Metro Pancake?

The correct answer is The 12 Inch Challenge because this nickname specifically refers to the impressive size of the Metro Pancake, which measures 12 inches in diameter. This unique characteristic sets it apart and emphasizes not only the pancake's size but also the challenge aspect, enticing customers who enjoy hearty meals or are looking to take on a culinary challenge.

In comparison, while names like The Big Flapjack, The Mega Stack, and The Monster Pancake convey notions of size and indulgence, they do not accurately represent the specific challenge associated with the pancake at Metro Diner. The 12 Inch Challenge effectively captures both the dimensions of the pancake and the competitive spirit it inspires in diners, which is a key part of the dining experience at Metro Diner.
