This restaurant is so far one of the better places I've eaten in Hawaii. There is a mix of Korean and Japanese food on the menu.
Food: My favorites: Butterfish, Spicy Ahi, Unagi and Kalbi Short Ribs . The butterfish is prepared just right, neither under nor overcooked. The self-proclaimed Spicy Ahi is everywhere on the menu and is served salad, rice, or on the side. The spice is a medium spice to me, but may be too much for others. *Note* You can request for less spice when you order this item. The unagi is ono and served hot. I suspect this is prepared and lightly toasted in a oven for that crisp taste. Like the rest of the nigiri sushi; unagi is very generous in size. I had the hamachi (yellow-tail) and ikura (salmon egg); both sushi was served in larger portions than other restaurants. A few times I had the Kalbi ribs in a combination (you can select a number of dishes in a bento-style serving) which just hit the spot. These beef short ribs have very little to none fat on the bone. The chirashi is also recommended. Spicy Ahi serves a variety of drinks (non-alcoholic and alcoholic) but also is BYOB - you can bring in your own drinks into the restaurant.
Service: When this place gets busy it can be difficult to get additional water/tea so during the heavy times you will see additional wait staff. Overall the service is excellent during lunch (less busy) and dinner.
Ambiance: This is a family restaurant and very popular with local residents of Hawaii. The restaurant can roughly handle 40 people total. There is a large plasma tv mounted but no sounds emitted only captions. K-dramas anyone?
Bottom Line: This IS one of the first places you want to eat (if you haven't been home for a while) after you get off the plane. Quality food with reasonable prices.
