The Crab Shack is a seafood restaurant in Beach City that is first introduced in "Fusion Cuisine" and is later referenced in "Love Letters." It is separate from competing Beach City restaurant "The Original Crab Shack," which appears in "Laser Light Cannon" and "Onion Trade." It serves breadsticks, though it is unknown whether they are unlimited or not.
The Crab Shack has a marina aesthetic and layout, with main back deck for outdoor seating that is connected to a dock. It has two stories of indoor space, and a take-out order window facing the water. Inside the restaurant, several taxidermied fish are displayed on wall mounts on either side of the restrooms.
Connie and her parents, Dr. Maheswaran and Doug Maheswaran, have dinner with Steven and his "parents", Greg and Alexandrite (later revealed to be the fusion of Garnet, Amethyst, and Pearl) at the Crab Shack.
Jamie asks Garnet to "dinner, or maybe lunch" at the Crab Shack in a letter.
- Ricky, the manager of Le Hotel in Empire City, used to work here. It's revealed in "Mr. Greg" that he apparently quit and moved to Empire City, taking a job at the hotel and has become the manager since his last appearance.
- It is most likely a reference to the "Joe's Crab Shack" restaurant chain, as well as several other seafood-based restaurants.
- It might also be a reference to the seafood restaurant of the same name in the TV show My Name Is Earl.
