Dining Outside the Home: Kenji Burger in Kapaa, Kauai. It’s always good advertising when a sign boasts: “We use 100% Kauai grass fed beef,” especially if you prefer a fusion diet of healthy meats and vegetables. Grass fed beef translates into leaner burgers. At Kenji Burger, the Japanese mix of Asian cuisine with American favorites provides a taste extravaganza that’ll leave your head spinning. Think outside the box. Teriyaki burgers, misoyaki fish sammies, spicy poke bowls, loaded sushi burritos, and furikake fries. This is not your ordinary burger joint. See the maneki-neko Japanese cat figurine, with its paw raised, perched on the counter? It definitely brings good luck. Perhaps you’ll give them a try. Kenji Burger is spot on.
