Hip, busy, and on the ocean -- this is what dining in Waikiki should be. There's hardly a time when the open-air dining room isn't filled with good Hawaiian music. Duke's is popular among singles, but don't dismiss it as a pickup bar -- its ambience is fun for all. Named after fabled surfer Duke Kahanamoku, the casual, upbeat hotspot buzzes with diners and Hawaiian-music lovers throughout the day. The lunch and Barefoot Bar menus include pizza, sandwiches, burgers, salads, and appetizers such as mac-nut and crab wontons and the ever-popular grilled chicken quesadillas. Dinner fare is steak and seafood, with decent marks for the fresh catch, prepared in your choice of five styles. Live entertainment is featured nightly from 4pm to midnight, with no cover. Be prepared to fight the crowds if you come at sunset.
