You'll probably drive through Hanapepe to visit Waimea Canyon (which you absolutely should do). If so, stop at Ishihara Market for more poke. Because you can't have too much poke in Hawaii. They have a large selection of poke - more than Pono or Koloa Fish Market - kimchi snails...anyone? The seafood used is fresh. Good quality poke that you shouldn't miss if you're driving through.
