- Breakfast smiley faces: Two sunny-side up eggs for eyes, three strips of bacon for the smile, and a strawberry for the nose.

The sign for The Best Diner in the World is supposedly made out of metal materials. In a sky blue, neon-type sign, small letters can be seen saying "THE BEST IN THE WORLD". In between the neon sign, it has the word "DINER" in bold, large, magenta letters. It has a grey metal frame supporting it, and it is on top of the building.
- A breakfast smiley face from the diner is used to represent the episode "Keystone Motel" on one of the StevenBomb 3 promo images.
- The diner's name is similar to the common restaurant practice of saying they are the best in the world.
