Oahu is undergoing something of a renaissance at both ends of the dining spectrum. You can splurge on world-class contemporary cuisine at destination restaurants and explore local flavors at popular, very affordable holes in the wall. Whatever your taste and budget, you’ll find places that pique your interest and palate. You may wish to budget for a pricey dining experience at the very
top of the restaurant food chain, where chefs Alan Wong, Roy Yamaguchi, George Mavrothalassitis, Chris Kajioka, and others you've seen on the Food Network and Travel Channel put a sophisticated spin on local foods and flavors. Savor dishes that take cues from Japan, China, Korea, the Philippines, the United States, and Europe, then are filtered through an Islands sensibility. Take advantage of the location and order the superb local fish—mahimahi, opakaka, ono, and opa.
Spend the rest of your food dollars where budget-conscious locals do: in plate-lunch places and small ethnic eateries, at roadside stands and lunch wagons, or at window-in-the-wall delis. Snack on a musubi (a handheld rice ball wrapped with seaweed and often topped with Spam), slurp shave ice with red-bean paste, or order up Filipino pork adobo with two scoops of rice and macaroni salad.
In Waikiki, where most visitors stay, you can find choices from upscale dining rooms with a view to Japanese noodle shops. When you’re ready to explore, hop in the car, or on the trolley or bus—by going just a few miles in any direction, you can save money and eat like a local.
Kaimuki's Waialae Avenue, for example, is a critical mass of good eats and drinks. There you’ll find an espresso bar, a Chinese bakery, a patisserie, an Italian bistro, a dim-sum restaurant, Mexican food, and a Hawaii regional cuisine standout (3660 on the Rise)—all in three blocks, and 10 minutes from Waikiki. Chinatown, 15 minutes in the other direction and easily reached by the Waikiki Trolley, is another dining (and shopping) treasure, not only for Chinese but also Vietnamese, Filipino, Malaysian, and Indian food, and even a chic little tea shop.
Outside Honolulu and Waikiki there are fewer dining options, but restaurants tend to be filled with locals and are cheaper and more casual. Cuisine is mainly American—great if you're traveling with kids—but there are a handful of Italian and Asian places worth trying as well.
