I will be visiting Oahu April 1-15, staying in Waikiki (with in-laws & it's free) and likely doing some eating in. I've looked at restaurant recommendations already but couldn't find any suggestions on where to buy sashimi. I think I could just eat that for a week though I'd have to go shopping for it each day to keep it fresh.
I'd appreciate if you could tell me if I could get there by public transport (bus) or if I'd have to drive. We will be renting a car part of the time but not the entire time we're there.
