I was with a friend for two weeks in Oahu, we saved Rainbow Drive-In until our last night. We fell in love with Hawaii and the friendliness/peacefulness and were excited to try Rainbow, as we had many people recommend. This was the only experience in our two weeks interacting with anyone (tourist/restaurant employee/hospitality, etc) that was so rude, it left us in shock. I don’t eat meat and ordered the vegetarian chicken bites. When it came out, it was chicken on a bone. I understand mistakes happen and have never been upset at something like this. I was told by Cheyenne (sp?) that if I wanted vegetarian chicken, I should have ordered vegetarian chicken. I said I did order vegetarian chicken, I specifically said vegetarian chicken Karaage when I ordered. I was then told if I wanted vegetarian chicken, I would need to place another order, to which I did and paid, as my friend had her food and I was at a loss for words. I was then laughed at it after I said I was upset (I had another customer tell me this). I would check into the way customers are treated by reviewing the evening of 9/9/23 about 40 minutes before closing. Great food, great atmosphere, poor customer service. I was in the restaurant industry for 15 years and always give someone the benefit of the doubt, you never know what kind of day someone is having personally, however this was an experience that will make me choose not to recommend this restaurant to friends that visit Oahu.
