Rainbow Drive-In is a well known place for tasty Hawaiian mixed plate lunches at great prices. This place is always packed. We had the Mixed plate which consisted of chicken katsu, mahi mahi katsu, and BBQ beef. One thing that stands out is the quality of the meat, which adds to the experience. The slush was really good. It reminded me of an Icee with a fruit punch flavor. Lots of people were ordering loco moco and the beef stew special as well. The Mixed plate was only $7.25, a great deal. Recommended!
