The Loco Moco puff: Meatloaf, a runny sunny side-up egg, GRAVY, served in a cream-puff shell. If it had bacon + cheese in it, the deal would've been sealed. In retrospect I should have tried it, but passed because it was late in the evening.
Still, quite a submission to the pantheon of cardiac cuisine. I wonder why it is that Hawaii seems to have such an awesome array of food that is spectacularly unhealthy (but of course tastes fantastic)?
