The Krusty Krab

The Krusty Krab is a fast food restaurant in the city of Bikini Bottom, founded and owned by Eugene H. Krabs (better known to most as simply "Mr. Krabs"). This restaurant serves as the center of all Krusty Krab Inc. establishments. It is the most popular restaurant in Bikini Bottom. The restaurant's reason for popularity is the Krabby Patty, a burger with a very top secret recipe, which has almost always been the signature Krusty Krab dish. There are only two current employees at the restaurant: SpongeBob SquarePants (fry cook) and Squidward Tentacles (cashier). The Krusty Krab's main business competitor is the Chum Bucket, owned by Sheldon J. Plankton, Mr. Krabs' worst rival. While the Chum Bucket, the restaurant's only competitor usually fails, there have been some short times when the Chum Bucket wasn't failing. These infrequent short periods of time are the only times when the Krusty Krab has any competition.
