Richard Gilman of Newsweek says, "Cabaret is serious, which is to say it accepts the premise that mature themes aren't inimical to the musical genre. It is also fun in a salty, grown-up way - sensual, elaborate, honest and yeasty, full of accurate perceptions translated into sharp and savory theatre."
Richard Coe of the Washington Post writes, "With that totality at which our musical stage is so adept Cabaret evokes the bizarre atmosphere of Berlin when the Nazis were breaking the thin crust of a dream world. Hal Prince...again has created an imaginative fascinating musical drama."
Richard Watts, Jr. of the New York Times declares, "It is the glory of Cabaret that it can upset you while it gives theatrical satisfaction It is disturbing, provocative, meaningful, believable and highly entertaining."
