Fancy! is a restaurant located in Bikini Bottom, Pacific Ocean. Mr. Krabs, Squidward, Mrs. Puff, SpongeBob, Patrick, and Mary and her mother come here. The main chef at Fancy! Is Mr. Le Schnook. At Fancy!, there is live music preformed by scuba divers. The only instrument that has been seen was a Piano played by a scuba diver in the episode "Krusty Love".
Fancy! basically looks like a giant ship-in-a-bottle. It also has a giant sign at the top that says "Fancy!" on it. It is presumably on the opposite end of town from the Krusty Krab, seeing as Mr. Krabs mentions it being "someplace far away".
Obviously it was rebuilt because in "Chocolate with Nuts", SpongeBob, Patrick, Mary and her mother went to the restaurant and booked out the whole restaurant just to dine there. In that same episode, Squidward attempted to get in although he was not allowed to. SpongeBob has once rented the place using Tom's money and did so with Patrick.
