Kalypso may be your best bet in Hanalei. Or the restaurant at Hanalei Bay Resort condos in Princeville (that's where we usually stay). I just don't recall any other places with TVs set up for game watching up that way.
There might be better places if you're out and about on the island. Maybe Kauai Island Brewing if you're down south. Or somewhere in Lihue or Poipu.
