We are going to the big island soon with our kids. We will be in Kohala, Volcano and Hilo. We like local authentic food and would like to know about the lesser known local places. We love sushi and hope to find some good places. We will probably try some of the more expensive places such as Roy's and Merriman's. We dont mind splurging for something really special, and we realize that eating out is very expensive in Hawaii, but we expect great food, service and atmosphere for big money! What places should we avoid?
