A friend and I will be visiting Hawaii in a few months to hike around the volcanoes on the Big Island. We will also be a few days in Ohau. I have found many good threads about high end dining on both islands. My question has to do with dress codes in these high end restaurants. Since we will be packing light, the best clothes we'll have are polo shirts, running shoes, and fairly presentable hiking pants. It seems like many of the top restaurants in Hawaii accept casual dress, but which ones do not? Thank you very much for your assistance.
