The Sea Chicken Shack
Their menu is basically burgers, fries, and soda.
Their Policy is Head Bands = No Service.
They have a commercial quoting that they are the "Best Restaurant in the Sea", which made people go there but it really turns out that the shack is rust bucket dump and their customer safety is awful because Billy sat on a chair and it collapsed. But it seemed he was unhurt as he drank a soda after falling down.
Their Statue is pretty much the only reason that they are popular. SpongeBob climbed the Statue and seemed to enjoy it. It is like some sort of jungle gym.
