Keo's   In the 1970s, stars like Robert Redford dined on Evil Jungle Prince at Keo's, then in an old, white wood house on Kapahulu Avenue. The building is long gone and Keo's is now in Waikiki, but no one can deny that Keo Sananikone, a Laotian by birth, is the father of Thai food in Hawaii. Educated in the United States, he understood what Western diners wanted and gave it to them: flowers and light, tablecloths and English-speaking servers happy to explain the menu. The Sananikone family restaurants Keo's, Keoni's, Mekong I and II continue to please. The Kuhio Avenue flagship with its breezy windows opening on the street, orchids and celebrity wall of photos shows Sananikone's flexibility, offering American and Asian breakfasts, Thai lunches and dinners.  2028 Kuhio Ave. 951-9355. 7 a.m.-noon daily, 11 a.m.-2 p.m., 5-10 p.m. Sundays-Thursdays; 7 a.m.-noon daily, 11 a.m.-2 p.m., 5-10:30 p.m. Fridays-Saturdays.
