The plate lunch, which has its roots in Hawaii’s plantation days in the 1880s, is an economical and gut-filling choice. It includes an entrée, like teriyaki chicken or steak, served--usually in Styrofoam--with a scoop of rice and a scoop of macaroni salad. Ask any local for his or her favorite joint--everybody has one. One consistent star is Honokowai Okazuya Deli in Lahaina. You can’t go wrong with one of its lunches featuring ono or mahimahi with lemon-caper sauce.
