I noticed that there were a few places on Kauai that have somehow not been mentioned, so let me take the time to fill you in on the real treats the island has to offer.
1. Mermaids in Kappa has AMAZING wraps and gourmet food served on paper plates. Its casual and the food is fresh including the fish which they use in a Ahi Nori wrap which is probably the best thing on the menu (seared fresh ahi, nori, wasabi sauce, cucumbers, rice, and avo, if in season, all wrapped in a spinach tortilla). Do not pass this place by!!!
2. Moloaa Sunrise Fruitstand in between kappa and kilauea has delicious thick smoothies. Try the Taste of Hawaii smoothie which consists of fresh fruit, yogurt, dates, macadamia nuts, coconut and juice. There sandwhiches are ok but the smoothies or fesh squeezed juices are not to be missed.
3. Kintaro's in Kappa has the best sushi on the island hands down. Try the Hanalei roll or superdup. Get there early as the wait can be as long as one hour.
4. The fish market in Kilauea has great food for lunch. Big portions and tasty fresh fish make this another must. Definitely check it out.
