There is no ambience to speak of, and your water is served in unbreakable plastic, but if you're searching for local fare, Kuhio Grille is a must. Sam Araki serves a 1-pound laulau, made with Waipi'o Valley-grown taro leaves and pork, alongside "loco" plate lunches and grilled meats. This diner at the edge of Hilo's largest shopping mall opens as early as 6 AM.
