Founded in 1961, Rainbow Drive In delivers on the nostalgia with its iconic rainbow neon and school-cafeteria-style seating. Surfers and old-timers make this spot their meeting place, catching up over Hawaii-style plate lunches: two scoops rice, one scoop mac salad, and hearty portions of meat such as shoyu chicken, chili, or the Hawaii original loco moco (a hamburger patty over rice, topped with brown gravy and an egg).
