the Krusty Krab has become one of the most successful restaurants in the city. In the show, SpongeBob calls it "the finest eating establishment ever established for eating". Mr. Krabs frequently exploits his restaurant's popularity, such as engaging in price gouging and charging his own employees for use of the building's services. In the season 3 episode "Krusty Krab Training Video", the Krusty Krab building is shown to have originally been a run-down retirement home called the Rusty Krab, which Mr. Krabs acquired and converted into a restaurant.

Mr. Lawrence, a show writer and Plankton's voice actor, explained that the show's writers are not allowed to depict fish as food; he stated that there is no meat served in Bikini Bottom except at the Chum Bucket. Tom Kenny, the voice actor for SpongeBob, joked: "Krabby Patties are hummus!" Some commentators suggest that there is actually no secret ingredient, pointing to Mr. Krabs' miserliness. A writer for Hollywood.com believes that it is "all a ruse that crafty Mr. Krabs came up with in order to stop Plankton from focusing on [t]he Chum Bucket. It's legitimately
