Trying to plan a Hawaiian vacation, and great food is a top priority. We are on the fence between Kona Coast, Kauai, or possibly Maui. Which area has the best mix of fantastic local stands, casual fare, and also 4-5 star restaraunts and gourmet shops? What are some "must eats?" of each area? We eat pretty much anything, so let the suggestions roll in! BTW, we are planning a late June vacation.
