Look for Maguro Brothers in here. Far back, ocean side corner. Awesome Ahi and Maguro Bowls. They also have Musubi, (uncooked) Misoyaki Butterfish & Misoyaki Salmon.
This market is located on Kekaulike Mall, a PEDESTRIAN ONLY ZONE bordered on the Mauka (mountain) side by Hotel Street and on the Makai (ocean) side by King Street.
