The Designated Area Where You Are Permitted, by Man Ray, Your Ruler, to Obtain Sandwiches Using Man Ray Dollars is the alternate version of the Krusty Krab that only appears in an alternate timeline in the episode "Back to the Past."
It is in the shape of a old New England lobster trap. It is made completely of metal. On the roof, there is a metal chimney. On the left side, there is a box with a tube that connects to the interior of the building. On the front, there is a large painted face of Man Ray. Next to the building, there is a metal sign that has a white background and red letters that read the name of the building in capital letters.
The dining room has the same general layout as the Krusty Krab, but with metal walls, floors and tables. There are no windows in the dining room that look outside, and there is a large screen that displays Man Ray for him to talk to the customers.
The kitchen is similar to the Krusty Krab, but it is made of. The Main Universe Mermaid Man and Barnacle Boy were buried in the kitchen.
