6. Goody Goody Diner - St. Louis, MO
The Goody Goody Diner started off as a root beer stand and changed to a diner when the Connelly family took it over in the 1950s. They have perfected their diner menu with omelets are thoughtfully constructed to give you a flawless combination of flavors. Our favorite item on the menu is the Wilbur Omelet, which is packed with green peppers, onion, hash browns, and tomatoes, and then topped with chili and cheddar cheese.
