There are many iconic places to eat on Oahu, and Rainbow Drive-In is one of them. Serving up a bunch of local favorites, it is known for plate lunches that come with rice, heavy macaroni salad and your choice of meat. Choose among spam and eggs, hamburger steak or shoyu chicken. If you can't decide, snag a bento box or a mixed plate: teriyaki BBQ chicken, mahi and some boneless chicken. Rainbow is also famous for its loco moco plate, which is hamburger and egg smothered in thick gravy. But if that is too big for you, downsize to a bowl. Want to cool down while eating your plate lunch? Grab an ice-cold slushy float, a strawberry iced drink with vanilla ice cream.
