Old Honolulu @ it's best!.
Do not, i repeat, DO NOT enter if your mind is closed, you like pretentious places or you can't hang with the locals. However, if you want an authentic dive experience in the oldest bar in Honolulu (that's actually true) this is the place to go. Beer is super cheap and there is always something to see, either in the bar or, ehem, the "action" on the streets just outside. I love to imagine the bar back in the forty's when the sailors just came off the ship. All you have to do is be friendly, strike up a conversation with one of the regulars and relax!
