A new outpost of a bikini barista bar has been deemed too hot to handle in American Canyon, running afoul of local zoning codes and getting its license yanked as a result.

The controversial Bottoms Up Espresso kiosk opened at 3939 Broadway in December, replacing the Caffino kiosk that had been in operation there for the past 10 years, Community Development Director Brent Cooper told the Times Herald.

But Tuesday, members of the American Canyon City Council convened to discuss whether Bottoms Up was functioning as an adult business, a violation of local zoning codes, the Napa Valley Register reported.

It's not the lattes that have the councilmembers whipped up into a lather. Rather, it's the scanty attire the baristas wear at the store's other locations. Councilmember David Oro showed the room a photo from one of the chain's open outposts to make the point that the outfits were too provocative.

City officials first announced plans to revoke the shop's license based on the allegedly scanty dress of the baristas back in January.

Opponents of the kiosk argued that it is an adult entertainment business, and thus more akin to a strip club than a Starbucks when it comes to zoning rules.

According to the American Canyon city code, if a performer does not completely and opaquely cover certain "specific anatomical areas," which include the butt, breast below the areola, and pubic region, a business may be classified an adult-entertainment business. "Discernibly turgid" male genitalia also fall under the list, regardless of whether it is covered, and how opaquely.

An attorney for the franchise has said that they just want to sell coffee and pastries, and argued at the city council meeting that no employee of the city had actually observed employees at the kiosk in the allegedly provocative attire, according to the Register.

"No Bottoms Up personnel had ever been present in the inappropriately described adult entertainment 'costumes,'" wrote attorney Ralph Andino in a brief.

The city council did not appear to be persuaded, voting unanimously to uphold the city manager's decision and revoke Bottoms Up's business license.

Bottoms Up Espresso currently has locations open in Chico and Marysville, and is in the process of expanding to Arizona, according to the company website. According to Yelp, they have open locations in Tracy and Patterson.

Similar obstacles to the ones that surfaced in American Canyon arose when a chain called Pink Pantherz Espresso opened an outpost in Redwood City last September, adding to their existing locations in Modesto, Fresno and Fremont.

There, too, the zoning code requires butts, genital areas and breasts below the top of the areola to be opaquely covered and proscribes the appearance of erect male genitalia.

Disgruntled residents delivered a 2,000-signature petition opposing the baristas' attire, and the owner decided to modify the dress code as a compromise. It's not clear if that option is on the table in American Canyon.
