When couple Jenna Harvey and Ryan Woods graduated from UC Davis, they decided to create their own jobs. "It's not in our character to throw up our hands and say, 'Well, we tried,'" Harvey says as she remembers doggedly planning a 400-square-foot shaved-ice shack with Woods and their friend Steffen Haro. Their dream quickly evolved into a shop nearly three times as large, complete with an espresso bar, a kettle-corn popper, and a drive-up window. Named Pura Vida for the Costa Rican phrase that captivated Harvey during a charitable trip in 2007—"Locals say to them it means 'live pure,' and we like that"—the affable staff douses fluffy curls of ice with sweet fruits, puckery sours, and an array of sugar-free flavors accented with ice cream or marshmallows. Hot and iced coffees, which Pura Vida hopes to someday source directly from Costa Rica, enliven palates in between bites of kettle corn, which Woods pops from whole-grain kernels. As soft music floats through the red-walled storefront, free WiFi ricochets across the hand-built bamboo counter and onto patio tables perched beneath a shady pitched awning.
