where is a good sushi bar/restaraunt?

I haven't been yet, but Tsukiji Fish Market and Restaurant at Ala Moana looks good.

Sorry I don't know about Oahu only Maui. I know on Maui San Sei's is good but for Oahu I'd have to ask my sisters since they are the ones living there. :)

I don't do seafood (I'll eat a ton of cucumber maki though :teehee)

Here are a few you can check out.

1. Irifune at 563 Kapahula Avenue in Honolulu offers reasonably priced sushi in an offbeat, eclectic environment. They do not serve alcohol, but you are welcome to BYOB.

2. Yoshitsune Restaurant at 2586 Kalakaua Avenue in Honolulu attracts tourists and locals alike, particularly for their mouthwatering Unagi. It’s also down the street from the Waikiki Trolley.

3. Sushi Sasabune at 1417 South King Street in Honolulu prides itself on using the best seasonal fresh fish to capture the flavors and colors of Japan’s 300 year old sushi tradition. Its sister restaurant in Los Angeles was voted LA’s best sushi restaurant by Los Angeles magazine in 1997.

4. Tokkuri-tei at 808 Sheridan Street in Honolulu is a local favorite for its authentic sushi menu and extensive selection of sake. Menu highlights include the salmon nigiri and hamachi kama.

5. Wasabi Bistro at 1006 Kapahulu Avenue in Honolulu offers an upscale dining experience with excellent service and an authentic Japanese flair.

6. Yanagi Sushi at 762 Kapiolani Blvd. (Cooke St.) in Honolulu serves up innovative takes on the traditional sashimi and rolls. Locals love the dynamite, which is a succulent seafood creation on a clam shell with onions, mushrooms, and minced clams. Kanpai!
