Food in Japan was really delicious. The restaurant below is right outside Chatan and is called Four Seasons. It reminds me of Benihana Restaurant in Salt Lake because they cook all your food on a hot grill right in front of your group. This type of cooking even entertained our three year old grandson. We sampled each others entree and the chicken dish was a favorite.
Gajumaru otherwise known as The Treehouse Restaurant in Naha was also a fun place to eat. The tree shape isn't from lumber but from a lot of concrete which is what most of this island's architecture is made out of. The views from the top floor of this restaurant are of the Naha harbor and are pretty amazing. We each had a good lunch starting with a Japanese salad bar and all you could drink basic beverages.
Sam's By-The-Sea has a view of The Nakagusuku Bay (1-41-15 Awase, Okinawa 904-2172, Okinawa Prefecture) had really good food. One of our favorite things was the curry soup. This crazy skull head was given to our grandson filled with his drink from the children's menu. I personally thought it was creepy.
One restaurant not far from Kadena my daughter and I enjoyed was really unique. You ordered your meal from a vending machine located at the entrance and then the meal was brought to your table. My husband didn't like it because he said it was soup and it was really deluxe ramen and delicious!
