I have been going to Wa's for years. It was recommended to me by my acupuncturist who spent 7 years in Japan who was married to a Japanese lady. He said it was the most authentic place in town. (unlike other sushi places who actually have Korean sushi chefs).
The service is always attentive, the menu is varied enough to please the most adventurous and cautious. I really like all the wonderful food served on the unique stoneware dishes. the Sake and beer always tastes better in a cup that I get to pick!
