The most famous Japanese restaurant in Wanaka (introduced on the travel website) is run by a Japanese family. There is a large kimono hanging on the restaurant wall, which is very easy to recognize. All Japanese food is served: ramen, fried rice, sashimi, sushi ...... is exactly the same as in Japan. The proprietress and her daughter act as waiters and cashiers. The price is expensive and tastes good. Worth a try.
