Bubba Burgers in Hanalei. My pick for the coolest burger joint in the world.

According to their web site, they have an agreement with the health food restaurant next door -- Bubba won't sell anything healthy and the health food restaurant won't sell anything that tastes good.

You can find more Bubba philosophy ("We refuse to sell any hamburger that costs less than a can of dog food") at their web site: www.bubbaburger.com
