We can't imagine Anahola without this roadside burger stand; it's been serving up hefty, all-beef burgers for generations. (And now there are Boca burgers, for vegetarians.) The teriyaki sauce and blue cheese are only part of the secret of Duane's beefy, smoky, and legendary ono char-burgers, which come several ways: teriyaki, mushroom, cheddar, barbecue, and the Special, with grilled onions, sprouts, and two cheeses. The broiled fish sandwich (another marvel of the seasoned old grill) and the marionberry ice-cream shake, a three-berry combo, are popular as well.
