Pepsi is asking people out and about in Atlanta to sip from unmarked cups of Pepsi Zero Sugar and Coca-Cola Zero Sugar to decide which they prefer.

The PepsiCo brand is celebrating its refreshed logo hitting store shelves this week with a social media giveaway and collaboration with Dickies.

Pepsi is bringing its revived Pepsi Challenge to Atlanta from May 8–11, inviting locals to a blind taste test against Coke Zero Sugar at multiple city locations.
