This links for all my peeps back at home-home.
Some folks in Hawaii put together a site called Wow Grinds, where they compare the "best of" local favorites in a blind taste test, ultimately determining the best of the best.
According to Wow Grinds, the best shoyu poke on Oahu may be found at JJ Seafood in Kaneohe. Yeah. There's no way anyone in my family's willing to drive to Kaneohe for some poke, so it looks like we'll have to settle for No. 2, Costco!
