- Celia: "Thanks. So, uh, are we going anywhere special tonight?"
Mike: "l...I just got us into a little place called, um, Harryhausen's."
Celia: "Harryhausen's? But it's impossible to get a reservation there."
Mike: "Not for Googley Bear."
- —Celia and Mike
During Mike's dinner with Celia, Sulley shows up to tell Mike about Boo, the human girl who somehow got into the monster world. However, she breaks away from Sulley and makes her presence known to all the patrons, causing mass panic in the restaurant. The Sushi Chef calls the CDA for help, and they arrive at the restaurant and round up everybody inside for decontamination. Mike and Sulley manage to escape with Boo, but Celia is caught. The entire restaurant is then closed off from the rest of the city in a blue force field. It was after the incident in the restaurant that all of Monstropolis became aware of Boo's presence in the monster world.
The restaurant scene is also featured in Mike's company play Put That Thing Back Where It Came From Or So Help Me, where Mr. Bile participates as the Sushi Chef in this play.
- The restaurant is named after the famous stop-motion animator Ray Harryhausen. Such noticeable examples of Harryhausen's work include films like The 7th Voyage of Sinbad (1958), Jason and the Argonauts (1963), The Valley of Gwangi (1969), The Golden Voyage of Sinbad (1973), and Clash of the Titans (1981).
- In both the storybook version and storyboards of Monsters, Inc., the CDA blew up the restaurant, but because of the terrorist attacks on September 11, 2001, it was changed to the restaurant being quarantined under a force field in the finalized version of the film.
- Marlin from the next film Finding Nemo is shown on the wall behind the Sushi Chef in the restaurant. On an interesting note, Finding Nemo was released a year in a half.
- A billboard of the restaurant makes a cameo in Cars 2.
- The overall design of the restaurant resembles a Japanese sushi restaurant.
- The restaurant made a brief cameo in the short Tokyo Mater, complete with car-ified versions of Mike and Sulley that appeared earlier in a Cars version of Monsters, Inc. (Monster Trucks, Inc.) that was among the Cars versions of other Pixar films shown during the credits of Cars.
- The fact that the monster employees yell, "Get a paper bag!" whenever someone enters the restaurant may be a reference to the fact that Japanese employees at restaurants and other stores yell, "Irasshaimase!" whenever someone enters. A similar Japanese saying and interpretation shows up in Toy Story 2.
- In the original version of Monsters Inc, instead of put under quarantine, the CDA simply destroyed Harryhausen's.
- According to the directors in the Audio Commentary for the film in the original film Mike was supposed to propose marriage to Celia at the restaurant but it was scrapped.
