Kahuku Farms is an agri-tourism attraction in Hawaii that offers farm tours and operates a cafe. The cafe naturally features products and dishes that come from the farm. Here's their menu for iced drinks:

So ... what do you do when someone wants a Coke or Pepsi? In the case of Kahuku Farms, they just say "no." That may disappoint some customers, but Kahuku Farms is staying true to their brand. They're in the business of delivering a tropical farm experience. Last time I checked, Pepsi doesn't fit that brand image.
