The 1-Stage was introduced in 1993 with the first installation at the Irving, Texas restaurant. It is a traditional CEC Stage that, like it's name suggests, is a compact show that is restricted to the size of only one stage. The animatronic arrangement here is not unlike the other CEC Stages; Chuck E. Cheese, Helen Henny, Munch, Jasper and Pasqually lined up from left to right in that order, in front of flat buildings and a starry backdrop. The size of the show itself takes up very little of the Showroom floor, creating a simple and yet effective form of animatronic entertainment. An interesting thing to note with this stage is that some, not all, 1-stages have a very unique feature, a turntable beneath the Chuck E. animatronic that rotates when the walkaround Chuck E. comes out for live shows, or to mingle with the young guests. The feature was meant to avoid the confusion of seeing two Chuck E's, one on stage and one on the floor. The turntable, thus, solves this problem by creating the illusion that the animatronic Chuck E. came off the stage.
As of September 2016, 49 1-Stages remain in operation in the United States and Chile.
The 1-Stage in North Wales, Pennsylvania no longer has the Wink, the Munch's Make Believe Band sign, or the brick backdrop behind Pasqually.
The 1-Stage in Pearl City, Hawaii no longer has the Wink and a flat-screen TV has been put in its place.
The 1-Stage in Lo Barnechea "Delano", Chile no longer features the Wink. It is also the only known 1-Stage outside of the United States, along with Lo Barnechea "12.352", Chile.
The 1-Stage in Manchester, Connecticut's Helen Henny animatronic now has New London, Connecticut's (now closed) old Helen mask.
The 1-Stage in Attleboro, Massachusetts had the last Tuxedo outfit before it was removed in 2014 and replaced with an Avenger outfit. The 1-Stage also has a unique mask on Mr. Munch and it has the Pizza Clock.
The 1-Stage in North Dartmouth, Massachusetts has Helen wearing shoes with pink shoelaces, Mr. Munch wearing shoes with purple shoelaces, and a unique mask on Pasqually.
The 1-Stage in Newington, Connecticut no longer has a Munch's Make Believe Sign, Helen, Jasper, Pasqually, and Chuck E. have unique masks, and it is the only 1-Stage in New England to have a 2-Stage background.
The 1-Stage in Durham, North Carolina has a unique valance.
The 1-Stage in Bel Air, Maryland has 2-Stage props despite the store never having a 2-Stage.
The 1-Stage in Columbus "Soldano", Ohio's brick backdrop behind Pasqually reads "Pasqually's Ametuer Hour Live" and the "Ametuer Hour" part is in a different font.
- Although the 1-stage, 2-Stage, and Road Stage are all very similar, there are often some additional differences with the band itself. For instance, sometimes Munch sports a personalized hat, sometimes no hat at all. Sometimes Jasper has got wrinkle-like facial marks on his face, sometimes he has none. Lastly, older restaurants sometimes have Jasper play a banjo, rather than his infamous "Flying Cheese" guitar.
- The "Wink" is a fiberglass decoration above all the CEC stages (and the 3-Stage as well), created in a shiny gold likeness of Chuck E's face. Coinciding with the playing showtape, the face will occasionally wink, often before an intermission or during another key moment in a showtape. The "ribbons" on the sides of Chuck E's head read at one time, "In Pizza We Trust", a slogan that also appeared on tokens, cups, and the sort. Today, most are repainted with red and white paint, while some still have "In Pizza We Trust".
