The rainbow diner is supposedly President Obama's favorite place to eat in Honolulu. There was a picture of him chowing down here on one of his visits here.
I don't know what the President ate, but I had the mahi mahi sandwich with tarter sauce and some fries. The Rainbow Drive-In is most definitely a dive and most definitely a drive-in. Although oddly enough, there is no drive up window. You have to park and get out of your car. Most people seemed to be doing take-out when we were there. I like it. I was not blown away with the food but, it was pretty good. It is an old time fast food place. Your food comes wrapped in paper and in a paper bag.
It was very popular with the local population. The line to order was probably a good 15-20 minutes. It was also raining on the day that we visited here which doesn't seem to happen much. They seemed to do a pretty good business selling t-shirts with their logo on it. I'm guessing that they have a mini cult following here.
The atmosphere was even more laid back than the rest of Hawaii, which is saying something.
I would rate the Rainbow Drive-In a 7.0. The food was okay and the atmosphere was okay.
