Hamura's Saimin   A perpetual 'Ilima Award winner, Hamura is as unprepossessing as they get, with worn Formica-topped counters, a tiny noodle soup-driven menu (each bowl outfitted with vegetables, hard-boiled egg, shreds of char siu and, if you want, teri sticks and/or won tons) and a family ambience on Kress Street, off the main drag in Kaua'i's capital city.  2956 Kress St., Lihu'e. 808-245-3271. 10 a.m.-10 p.m. Mondays-Thursdays; 10 a.m.-midnight Fridays-Saturdays; 10 a.m.-9:30 p.m. Sundays. No reservations. Cash only. $.
