A "let's save the business" film comparable to Malibu Bikini Shop, Bikini Drive-In, and so on, this exploitation comedy manages to be funny and sexy enough most of the time to please genre fans. The plot concerns porn star Marilyn Chambers (as herself) helping her friend save a vegetarian cafe by making the waitresses wear bikinis. Comic highlights are provided by Pamela Safaraba as Bettina Borg, a homely spinster on the neighborhood morals council who tries to shut down the bikini bistro with vociferous protests. But the point of any film like this is nudity and sex, and Bikini Bistro does okay in this department, with several scenes of nubile young hardbodies getting it on in closets and on rooftops. Okay, that is, until the final scene featuring the aging Chambers and a tweedy restaurant critic. It's shot in softer focus than usual, but enough of the ravages of time are obvious to be somewhat distasteful. Otherwise, this formulaic sex comedy is often funny and occasionally titillating assembly-line fare.
