We visited the town of Hanalei a lot for our choice of restaurants. There are many to choose from - every style, price, and taste.
Bamboo Bamboo: We received a $50 gift certificate from listening to the timeshare presentation to use at a restaurant/store of our choice. We choose Bamboo Bamboo. The restaurant is decorated completely with bamboo, including the chairs, glasses, plates, and tables. The food was delicious. My daughter and I shared seafood pasta. The average cost of a meal $20. Children menus were available. I would recommend returning to this restaurant. Visit their website at http://restauranteur.com/bamboo/.
Polynesian Cafe: This is located in the Hanalei Shopping center. Our favorite was the veggie wraps. All items are reasonably priced. There are lots of choices at this restaurant: sandwiches, ice cream, wraps, etc. Soft drinks and water are available. There is outside seating only.
Subway: This is located in the gas station in the Hanalei shopping center. It is just like the Subways on the mainland, but a little more expensive since it's in Kauai. It’s a great place to pick up sandwiches and then head to the beach.
Wishing Well Shave Ice: This is the best place on the North Shore for shave ice. It is located on the right side of the road coming from Princeville. They have a great choice of flavors. The wife owns the business and her husband works for her. Their claim to fame: "First on the island - Everyone else just copies." My favorite was the Tropical Paradise. A lot of customers got ice cream on the bottom of their shave ice. I didn't have a chance to try it but will next time when we go back to Kauai.
