The Zebra Bar is a chocolate bar heard advertised on the radio in Grand Theft Auto: San Andreas. It is marketed as being half white chocolate and deep dark chocolate. The bar is apparently manufactured by the Zebra Bar Candy Company where, according to Lianne Forget of WCTR News, people have been protesting at their factories for unknown reasons.
The bar is reintroduced in the HD Universe (this time a product of Candybox), where it can be seen being sold by street vendors in GTA IV and in convenience stores in GTA V. It is a clear reference to Lion Bar which has white chocolate and dark chocolate. It's slogan, "The Exotic Bar" is a reference to a penis.
