Also, a friend who used to live in Honolulu sent me to this place, which was probably the coolest restaurant I've been to in a dozen Hawaii trips. It's called La Mariana, deep in the industrial district -- no one would ever find it unless they were looking for it.
It's basically cut into the trees adjacent to a little marina for locals. Chairs with high wicker backs, rope nets with glass balls, a fish tank behind the bar -- it's an honest-to-god tiki bar from decades before anyone here ever heard of one. And it has live entertainment, two blind guys playing Hawaiian classics on a ukulele and a beat-up piano. You can picture sitting there in the '50s watching the Pan Am jets land.
