 The Sci-Fi Dine-In, located on Commissary Lane across from "Star Tours" and adjacent to ABC Commissary, opened on April 20, 1991 as one of the twenty new attractions opened at Walt Disney World to mark the complex's twentieth anniversary.The restaurant was created with a strong emphasis on theme, in emulation of the 50's Prime Time Café, which had opened two years prior.Disney hoped that the focus on theme would bring the Sci-Fi Dine-In the level of success that had been garnered by the 50's Prime Time Café.
