Diners, Drive-ins and Dives

Elena's (Waipahu, Oahu, Hawaii) • El Indio (San Diego, Calif.) • Blue Koi (Kansas City, Mo.). This trip, Guy's checkin' back on some family-run favorites. On Oahu, siblings with a brick-and-mortar spot now rollin' out their mom's Filipino food all over the island. In San Diego, a taquería scratch- makin' taquitos the same way for three generations. And a brother-sister team in KC still dishin' out off-the-hook, Asian-inspired eats.
