Louie and Regan Colburn’s Hawaiian luncheonette went from a walk-up window to a brick-and-mortar in what may well be record time — just a few short months upon its opening last year. And it was all thanks to poke. After all, as an island native, Louie comes by the house specialty honestly — which means that trend or no trend, shoyu or spicy, Ohana’s bowl is the real deal. But for the total package, throw in an order of Spam musubi and a can of UCC Kona Blend Coffee.
